The Impact on Cayey, Puerto Rico of the Spanish American War: The Evolution of a Place Called Henry Barracks


Introduction: This paper presents the results of a desk study of original documents on the impact of the development of a track of land for military use in Cayey, Puerto Rico. The paper is divided in four major segments: the Spanish Barracks (1897-1898), Camp Henry (1898-1909), The Cayey Naval Radio Station (1914-1932), and Henry Barracks Army Post (1910-1962). Desk Study: The investigators relied on interviews, pictures, and narratives of key informants that either lived, grew-up, or used the facilities of the Henry Barracks Army Reservation. This paper is a summary of approximately three thousand pages, pictures, and maps located in the National Archives and Records Administration (NARA) as well as documents from the Library of Congress of the United States and the Museo de Historia Militar, Madrid, Spain, and Army and Navy reports, general and specific orders, and Order of Battle documents archived in the libraries of the United States War College, Carlisle, PA., West Point Military Academy (New York) and the Naval Academy (Annapolis). Limitations: Most of the original materials such as logs, order of battle, and other original information was found in repositories in the United States, and dated from 1898 to 1967. A search of the Museo de Historia Militar in Madrid, Spain only had available information on the Spanish conquest of San Juan, and only rudimentary maps were found about the rest of the island of Puerto Rico. Summary of Findings: The study concludes the Spanish Government constructed a Barracks in Cayey in 1897. The Spanish troops remained in their Barracks until they were repatriated to Spain on October 18, 1898. The original reservation was set apart by Executive Order on July 7, 1903. An additional 372 acres were purchased in December 1903. The study concludes that the geographical evolution of this land has had a marked impact in the development of the town of Cayey and the Central Mountain Region of Puerto Rico.

1. Introduction

The discovery of Cuba, Hispaniola (Haiti and Dominican Republic), and Puerto Rico in the latter part of the 15th century, opened the doors to colonizing the south-eastern part of what is now Florida (a state in the United States) as well as Central and South America. Puerto Rico became a price holding for the Spanish armada, and the Galleons that transported riches from South America to Spain. Puerto Rico also served as a strategic defense/deterrent to protect Spanish interest in the Caribbean. San Juan, a small island in the north, remained the stronghold, where the Spanish Army settled its troops and built a fortification. The reminder of the island was protected by locally deployed Spanish Army elements who trained the insular support forces. One such post was located in Cayey, its primary role was to protect the crossroads between the four cardinal points of the island, as well as to provide an inland base where Spanish soldiers were sent to adjust to the tropical weather of the island.

This paper provides a historical overview of the role of the Henry Barracks Military Reservation in the development of the town of Cayey, Puerto Rico from 1898 to 1967. The paper describes the three main facilities in the Reservation: 1) the Spanish Fort, 2) Camp Henry (later renamed Henry Barracks), 3) Cayey Naval Radio Station. The paper presents a visual representation of how the Reservation changed and how changes in the structures are reflective of things to come.

Cayey is located in a valley in the central mountain range of the Island of Puerto Rico (Latitude: 18.1144, Longitude: 66.1681)3. It is located at the crossroads of major roads that permit travel and the flow of goods from the San Juan area in the north to Ponce, the second largest city, to the south. It is an entry point for the panoramic route that crosses the Central Mountain range and the catalytic point to some important events in the development of the Island.

By the 18th century Cayey became a town4. The self-defense of the Puerto Rican people had begun as far back in 1642, when Para-military groups were organized in towns and villages as the island population grew. Field Marshal Alejandro O’Reilly was tasked in 1765 with the responsibility of organizing an urban militia5 in order to provide safety and security to the population as well as to augment the Spanish soldiers at the Garrison when needed. The rule remained that only Spanish soldiers would live in the Barracks established throughout the Island.

In 1887, there was a request from the Governor General D. Romulo Palacios to the Central Government in Spain to establish a military hospital. The intent was to provide a place for troops who had recently arrived from Spain to adjust to the climate and the tropical illnesses. A decision was made to construct a Spanish Barracks in Cayey for 250 men, a HQ component, and two Infantry Companies in 15 acres of land on a hill overlooking the town6. The proposed Barracks was to be composed of ten one-story buildings. The reason for selecting this site was threefold: the availability of raw materials locally7, low cost of workmanship, and the appropriateness of the climate. Construction began on 5 April 18978.

The Barracks was occupied by recently arrived troops from Spain, who spent a time in Cayey getting acclimatized for service in the San Juan Fort (El Morro). In 1898 there were two Infantry companies (293 men) and about 47 soldiers working in the hospital. In addition there were 243 soldiers belonging to the Sixth Battalion of the Provisional Guard. All the personnel in the Barracks were Spanish, and responsible of the defense of the Guayama and Aibonito road in the event of an invasion.

2. Preparing for the Defense of Cayey

Julio Cervera Baviera, the commanding officer of the Engineers and Field Aide of General Macias was ordered to move the Sixth Battalion of the provisional guard from Cayey and a number of troops that had been transferred from Aibonito―a total of approximately 400 troops (see above the distribution of troops)―into a defensive position in the road from Guayama to Cayey. He set his Headquarters on the coffee plantation at the beginning of the narrows between Jajome and Guamani. The objective was to defend the Alfonso XII bridge (see photograph in Figure 1)9.

The Spanish forces set themselves up in the higher ground of the straits and at the sides of the Guamani Ridge. The Spanish forces were ordered to delay or stop the advance of the American forces from heavily defended terrain.

3. The American Forces March unto Cayey

In 1898, the Spanish American war brought the U.S. Army to Puerto Rico. The American force was organized into four columns (see Figure 2). General Brooke and his troops landed in Arroyo on August 1, 189810. The objective of the column was to advance to the capital San Juan through the center of the island from Arroyo through Cayey, thus over powering all Spanish Army resistance and capture the strategic cross- roads located in Cayey.

The columns of American Expeditionary soldiers move from Arroyo to Guayama and onto Cayey. These forces were members of the State Guard from Ohio and Pennsylvania11.

In the meantime, lead elements of, the 4th Ohio and the 3rd Illinois under the command of Gen. Brooke scouted the routes leading from Guayama to Cayey. These elements collided with elements of the Spanish Army near a bridge at the Guamani strait. The scrimmage lasted all day. The Spanish troops took positions along the hilltop and met the Americans with accurate rifle fire resulting in five American Soldiers wounded12. American forces maneuvered around the Spanish positions and by doing so, nullified enemy resistance along this route. The road from Guayama to Cayey was cleared13,14. The exchange of fire between the Spanish and the Americans resulted in three American soldiers and several Spanish troops injured. General Brooke’s soldiers captured the Spanish “Cuartel” in the town of Cayey on August 8, 1898, in route to an attack on the capital San Juan.

The morning of the 8th of August the valley of Cayey woke up to an impressive military display. General Brooke had positioned three batteries of artillery (Battery B, Pennsylvania, Battery A Missouri Artillery, and the 27th Indiana Artillery) on the hills from the Guayama road overlooking the town. Figure 3 above shows the cessation of hostilities shortly before the beginning of the attack on Cayey

He then proceeded to the Cuartel Español (the Spanish Barracks) with two Calvary troops from the 6th U.S. Calvary, Troop H, and Pennsylvania Volunteer Calvary15. There was no resistance offered by the Spanish Army and by noontime on that day General Brooke sends a message to the War Department: “Cayey taken”.

4. The Spanish Barracks (Cuartel Español) Becomes Camp Henry16

As a result of the treaty of Paris signed the 18 August 1898, Puerto Rico, Cuba and the Philippines were ceded to the United States as spoils of war. The Spanish empire had collapsed. The Spanish soldiers returned to their barracks in Cayey. They remained in quarters until they were repatriated to Spain on 15 October 189817.

This captured piece of real estate consisted of 15 acres of land on a hill east of the town of Cayey. It overlooked the entrance of the town of Cayey and thus controlling the strategic cross-roads from Caguas, Guayama, Salinas, and Aibonito. From that vantage point all activities of the town were monitored. The main building in the installation was 320 feet by 30 feet and was the largest building in the region. It housed the Surgeon General, Officers, and a 112-bed hospital (see Figure 4).

The largest building (Hospital) was located at the top of the hill, known as Hospital Hill (La Loma del Hospitalillo) by the locals18. Northeast of the hospital was the kitchen and a squad room with a capacity of 20 men (probably cooks and orderlies). Just below the top plaza was a Quartermaster stables with a capacity for 78 animals and a wagon shed with capacity of 20 wagons. Three smaller buildings in the same area accommodated the following: 1) the plumbers and a tin smith; 2) the QM barracks with a capacity for 17 men; 3) QM store house; 4) QM shops (26); 5) an oil house with a capacity of 5000 gallons. On the access road from the Hospital there were two wooden quarters that accommodated NCOs and two cavalry companies. At the bottom of the hill was the Headquarters and guardhouse19. In 1899, the San Cipriano hurricane destroyed the barracks. A new hospital was built on the bricks of the Spanish hospital. The American forces used the remnants of the Spanish Barracks after the 1889 Hurricane, and rebuilt ten wooden structures using the blocks and rocks from the quarry on the Post. The American soldiers were repatriated in 1901. The 2nd Battalion of the Puerto Rico Volunteer Infantry took over the Barracks on 23 February 190120. There were four companies (E, F, G, and H) assigned to Camp Henry (two infantry and two mounted).

5. The El Cayey Naval Radio Station (1912-1932)

In 1914 the Secretary of the Navy had planned to establish a high power station in

Cayey. Because of this decision, the southern side of the Henry Barracks Reservation was surveyed and chosen by the U.S. Navy for the establishment of a radio communication base. Cayey became one of five radio communication stations in the world (others were Cordova, Alaska, Arlington, VA, Cavite and Tutuila in Guam, and Pearl Harbor in Hawaii) that formed the most powerful chain of communications for the United States21.

In 1915 the Secretary of War had begun negotiations to transfer a track of land from the War Department to the US Navy22. In August 29, 1916 the War Department transferred a track of land from the Henry Barracks Reservation to the Navy Department by authority contained in the Naval Appropriations Act (39 Stat. Law 568). The Naval Reservation at Cayey Puerto Rico comprised 59 acres of land known as Magazine Hill transferred to the Navy in 191623.

On December 18, 1916 the White House approved the transfer of $400,000 for the construction of a protected High Power Radio Station in Cayey. The justification for this expenditure read “The island of Porto Rico is of extreme strategic importance in connection with fleet operations, due to its location. With a High Power Radio Station would ensure communication with the fleet, Europe, and South America to a greater degree than by any other means.”24 Figure 5 shows a map of the Naval Station with its three large towers and quarters for officers and enlisted men.

Congress approved a high power radio station25. The Naval Appropriation Committee disbursed the already approved $400,000 for the establishment of the radio station. The Secretary of the Navy reported for both in 1918 (Serial Set Volume 7495, House Document 1450, page 529), and in 1919 (Serial Set Volume 7703, House Document 729, page 357) for the construction of the High Power Radio station in Cayey. Three 620-foot towers of steel were constructed. On February 5, 1920 the High Power Radio Station was placed in commission26. In addition the following projects were developed at the Cayey Radio Station: 1) established a distant control for the Station, 2) moved one generator from Cavite in the Philippines to install in Cayey, and 3) enlarged the water supply for engine cooling purposes at an additional cost of $104,00027. The photo below shows the Cayey Radio Station in full operation. The Radio Station was run by General Electric High Compression Oil Engines (Type GM-52)28. On August 16, 1920, there was approval for additional work on the Radio Station. These included walks, sanitary facilities, hurricane doors and windows, and connection of the three engine driven generator foundations together with concrete to eliminate vibration29.

These personnel were moved to San Juan as a result of the Hurricane of 1928. They were never to return on a permanent basis to Cayey30, but rather would travel to the radio station as needed. The U.S. Army took over the care and protection of the Base.

The municipality of Cayey was looking at Magazine Hill (identified in Spanish language as “El Polvorin” (see Figure 6 and Figure 7) for expansion of the town and construction of a hospital. The municipality requested that the U.S. Government return Magazine Hill to the town since they had learned that it would not be used by the Navy31. Magazine Hill was transferred to the municipality of Cayey on March 5, 192332.

In 1918 the base was fully operational with 25 men per shift working three shifts. The station was used exclusively for receiving messages for the Commander for the Caribbean Fleet. The station received 5000 words daily33. Figure 7 shows the Powers of the Navy Station.

At Puerto Rico, the Greenland Plan34 called for development of a major operating base as the keystone of the Caribbean defense, with facilities to include a thoroughly protected anchorage, a major air station, and an industrial establishment capable of supporting a large portion of the fleet under war conditions.

Puerto Rico was to be the “Pearl Harbor of the Caribbean”, furnishing logistic support to outlying secondary air bases developed on Antigua, St. Thomas, and Culebra35. WW2 was just around the corner, and this required yet another adjustment to the Henry Barracks Military Reservation. The Navy Station was closed down, the towers dismantled, and the lands in the southern part of the Reservation were taken over by an Army that was preparing for war. Figure 8 presents the destruction of the last tower. By 1938 the El Cayey Radio Station was closed, and the towers were transferred to Isla Grande in San Juan where the high power radio station would be nearer the Command of the Fleet.

soldiers that served in the Puerto Rico Infantry Regiment and the weather. Puerto Rican men wanted to serve in the military for two reasons: 1) as a way to provide for their family with a steady income, and 2) the prestige of being a cut above other men in the society. As long as there was a need to accommodate the soldiers, there was a role for the Post37. The weather played an important role on the evolution of the Post and the construction of permanent structures. For example three hurricanes―San Ciriaco in 1899, San Felipe in 1928, and San Ciprian in 1932―had a major impact on the physical development of the Henry Barracks Army Post. Another important factor was the deployment of the 65th Infantry to assist in several little known campaigns in Central America called Banana wars38. Thus the Henry Barracks served as a training post for the Marines and other Army units with a skeleton crew in the Barracks.

In October 1898, with the creation of the American Military Government, the Military Department of Puerto Rico assumed control of Insular Military Affairs, and Cayey became one of the twelve posts that remained from the Spanish Government. On February 23, 1901, American troops were relieved from their duties in occupation of former military lands, and they repatriated to the United States. The 2nd Battalion of the Puerto Rico Provisional Regiment of Infantry39 was housed in Cayey under the command of Major R.F. Ames.

The U.S. Army inherited from the Spanish Army all the buildings in Hospital Hill: 1) a Barrack size structure (30 ft by 320 ft) built in 1899 used as a hospital and officers’ quarters; 2) the quartermasters’ stables erected in 1899; the 3) Hospital kitchen and squad room; and 4) an assortment of QM storehouses, a bakery, and a commissary. The custody of the post in Cayey was placed under the jurisdiction of the Second Battalion of Puerto Rican Regiment US Volunteers-Mounted Battalion40,41. In 1899, hurricane San Cipriano destroyed all the buildings of the former Spanish Barracks, now Camp Henry.

In 1901 two large barracks, the Officers’ Quarters, and the Post Exchange were erected. They were made of wood and had galvanized iron roofs. A guard House was erected in 1902 made of wood and a galvanized steel roof. In 1905 NCO Quarters were erected all wooden throughout and with galvanized steel roofs. In the same year, President Theodore Roosevelt made an Inspection visit to Camp Henry as depicted in Figure 9, taken with the President in the Hospital stairs of the Spanish Fort.

In 1908, the Porto Rico Provisional Regiment of Infantry was redesigned on 30 June as the Puerto Rico Regiment of Infantry and allotted to the Regular Army. The 2nd Battalion was in Cayey.

Two companies from the 2nd Battalion were deployed to the Canal Zone in 191742. The assessment of the Battalion Commander at the time of deployment was that “except for one building everything else would have to be rebuilt”43. Henry Barracks is situated in the center of the island. It is thirty-seven miles from the nearest coast, and all supplies of every kind had to be transported at a high cost over mountain roads by mule teams or trucks. The transport of freight and passengers was at great expense44. Henry Barracks was not the preferred spot for an Infantry regiment.

Figure 9. President Roosevelt visit Camp Henry U.S. Army the Post 1906 (Photo courtesy of the Library of Congress). LC-DIG-ppmsca-36399.

On February 24, 1919, Major Emmanuelli requested all buildings occupied by the Naval Stations to be returned to the Troops that were returning from the Canal Zone45. Lt Colonel Orval F. Townsend the Commander recommended that two companies of the Regiment be returned to Henry Barracks on or by May 24, 191946. On May 7, 1919 an authorization was declared for the construction of one-company size barracks in Henry Barracks at the cost of $12,75047. A recommendation was made to purchase land at Camp Henry. This land was north of the Reservation following a small ridge to the north and parallel to Route 1.

Noteworthy is the use of Stone houses found on the main routes from San Juan to the other large cities of the Island. They were called “Casa de los Camineros”. For a period of time it was assumed that the people that maintained the routes used these houses. We found a letter dated May 20, 1919, where Col Townsend requests the use of the houses along the road from San Juan to Caguas as sleeping quarters for military personnel responsible for guarding the main roads. Figure 10 shows the ruin of a roadside house that served as sleeping quarters for soldiers guarding the roads. This was a common request at that time especially for Calvary Troops doing guard duty in the main roads48.

Figure 10. Ruins of a typical “Caminero” Road House used by the 65th Inf. Calvary units while on guard duty.

In 1919, two companies (L and M) of the 3rd Battalion returned to Henry Barracks. The Puerto Rican Regiment became the 65th Infantry Regiment in 192049. Upon their return to Henry Barracks, they occupied the barracks that were reconstructed. While Henry Barracks served as a fully operational Infantry training camp, many of the 2nd Battalion troops deployed much time fighting in the Banana wars.

7. The Impact of San Felipe on Henry Barracks

On September 13, 1928, the Island of Puerto Rico was swept by a Hurricane named San Felipe. It carried sustained winds of over 160 miles per hour. Henry Barracks was destroyed50. The loss of a company size building that housed Co. M, 65th Inf. damaged the infrastructure, Quarters, and government and personal properties. All the building made of wood and galvanized steel were damaged beyond repair. This included all the buildings in Hospital Hill: Hospital, barracks, a Kitchen and Mess Hall erected in 1900, and wooden buildings with galvanized steel roof constructed in 1901 and 1905, and a wooden building constructed in 1919, when the troops returned from the Canal Zone.

A Board of Officers was convened to determine the extent of damages to Henry Barracks. The Board met on September 14, 1928 and found that the greater majority of the buildings damaged or destroyed were wooden with galvanized steel. The Board recommended that all buildings of the sub-post of Henry Barracks be replaced with concrete or a suitable material other than wood51.

On July 5, 1929 replacements for the buildings lost in the Hurricane the previous year were completed. These included the commissary warehouse, two Kitchens, and Mess Halls located on the land used by the Navy. In addition fifty-eight pyramidal tents were completed by December 1928. An electric light system was completed by April 1929, and a gasoline shed was completed in June 1929. The hay shed, wagon sheds, and Q.M. Shops were completed by March 1929.

Shortly after arriving at Henry Barracks, Mr. Ford52, a civil engineer working for the Quartermaster (his Job Title was Construction Quartermaster53), was presented with several layouts. He was confronted with two problems: 1) the standard plans for construction of an Army Barracks could not be fit into the contour of the land (the reader will recall that this was the land was north of the Reservation following a small ridge) to the east of the existing post that had been previously purchased in 1919), and 2) the terrain was made of about eight inches of black soil and solid rock. Any excavation would have to be done through solid rock. A new layout was developed following the contour of the land, with an effort to keep the floors at approximately the same level54.

With the Civil Engineer (Constructing Quartermaster) there was a Quartermaster company assigned to Henry Barracks. While they stayed on temporary quarters on the South side of the Post they interacted with the workers and the soldiers from the 65th Inf. They were called “Continentales”.

Funds to construct a hospital were approved by the 70th Congress on March 3, 1929, and the building was completed on May 9, 1931 at a final cost of $35,000. The hospital provided the facility for soldiers to be cared for near their battalion barracks; therefore, dependents did not have to travel to Fort Brooke for treatment.

In addition to the quarters for Officers and NCOs, on July 15, 1930 the construction of three barracks was begun. There were two one-company barracks (i.e., each accommodated one rifle company) and one two-company Infantry Barracks (i.e. accommodated the Battalion headquarters and a Machine Gun Company)55. The two-company barracks was completed on July 4, 1930. The two one-company quarters were completed on April 14, 1931.

By January 1932, the Constructing Quartermaster reported56 that twelve sets of Company Officers Quarters―one set of Field Officer’s Quarters and six sets of non- commissioned Officer’s Quarters―had been completed. These buildings were constructed to house officers and non-commissioned officers for one Battalion of the 65th Infantry. These new housing quarters substituted the temporary shacks, since the previous quarters were destroyed by the Hurricane of 1928. Figure 11 depicts the buildings on a map of Henry Barracks.

Figure 11. Map of Henry Barracks Army Post. NARA. Completion Report of Henry Barracks (1932) . NARA NM-19-391, Box 122.

Another set of construction included a Post Exchange Building, Post Headquarters building, Guardhouse and Fire Station, Stable and Hayshed, Wagon Shed, Store House and Maintenance Building, and a Recreation hall57. Construction of these facilities was completed between March and September 1931. The Recreation Hall was completed on February 24, 193258.

On May 17, 1932, the construction of the installation’s utilities was completed59. The following utilities were constructed: roads, walks, electric distribution system, a well, pumping stations, reservoir, water system, bridge, sewer system, sewage disposal plant, and grading and drainage.

In a Memorandum to the Chief of Staff initiated by Gen Douglas McArthur, Chief of Staff War Department dated October 28, 1933 with the subject being Disposition of Henry Barracks, Cayey, PR60, the guidance was as follows: “Relative to a transfer of Henry Barracks to Puerto Rico, the Commanding General, 2nd Corps, states that Henry Barracks is required for military purposes, and therefore neither the proposed sale or transfer to the Puerto Rican Government can be favorably considered by the War Department. The costs for improvements in Henry Barracks were in excess for $620,000”61.

Henry Barracks continued to be a sub-post of Fort Brooke until 1939 when Henry Barracks was declared a separate post62. Now Henry Barracks comprised of 264.54 acres to provide access to land where an infantry cadre could be trained in combat tactics.

By 1940 Henry Barracks had been developed into a complete military facility and fully functional infantry training ground. It housed the 2nd and 3rd Battalion of the 65th Infantry Regiment and the reorganized 2nd Battalion of the 25th Field Artillery, and a company of the 2nd Battalion 107 Quartermaster, called locally “Continentales”63. In this environment the members of the 65th Infantry Battalion and the “Continentales” often interacted together on the post and in social and religious activities in the town of Cayey.

The Post consisted of approximately 190 structures including facilities for 1000-yard rifle range ammunition storage, waste water treatment, vehicle maintenance, sanitary landfill, and various other miscellaneous support facilities as well as housing and improvements such as roads and utility systems64. The facility had crossed Route 1 and went well into the Cayey mountain range where the “Pepe Hoyo” neighborhood is developed today65.

The map shows Henry Barracks in 1937 presented in Figure 12 highlights for the reader several areas of interest such as the Spanish Hospital/Camp Henry in 1901, the Motor Pool, and Cemetery, the three main barracks in the north part of the Post, the Headquarters building, and the hospital (where many children were born). The western part of the Post includes the three High Frequency towers constructed sometime after the 1920’s and the control facility (large building by the track).

On 7 January 1943, the 65th Infantry Regiment deployed to the Panama Canal Zone where it joined the Panama Canal Department’s Mobile Force. In January 1944, the regiment embarked for New Orleans and then Fort Eustis, Virginia, in preparation for overseas deployment to North Africa. The 65th Inf regiment arrived in April 1944. The 3rd Battalion of the 65th Inf was detached from the regiment and sent to Italy and then to Corsica to provide airfield security for Army Air Forces units. Near the end of 1944, the Battalion rejoined the regiment, and training was resumed with emphasis on village fighting.

In August 1944, Company C was detached from the regiment and flown to France to

take over the security of the Seventh Army Command Post66. In September 1944, the remainder of the regiment received orders to move to France and landed in Marseilles and Toulan early in October. The Battalion went into combat on 12 December 1944 at Peira Cava in the Maritime Alps of southern France.

In March 1945, the 65th crossed the Rhine and remained in Germany as part of the Army of Occupation until October 1945, when it was ordered to Calais, France for the return home. The regiment arrived in Puerto Rico on 9 November 1945.

By 1950 Henry Barracks is preparing for war. Figure 13 shows an airport added that was long enough to support DC-3, C-45 and C-47. An aviation company can be seen in the plot of land south of the airport. By 1951, the 1st Battalion 296 Inf Regiment―a National Guard unit sister to the 65th Inf Regiment―was activated and assigned to Henry Barracks67,68. The units assigned to Henry Barracks were Hq & Hq Co., Company A, Company B, Company C, and Company D. This unit had its own motor pool. The unit and all ancillary resources were located in the southern part of Henry Barracks on the grounds recently vacated by the U.S. Navy. To accommodate this 1000 men plus four temporary barracks were constructed and 30 Pyramid Squad tents. Aerial Map 2 below

presents the 294th encampment area.

By 1955, the decision was made to de-activate Henry Barracks. It was passed from the control of the Army Corps of Engineers to the General Services Administration to dispose of the lands. The Puerto Rican National Guard Armory and the San Juan Geophysical Observatory are currently located on the site. The airfield has been closed. Reparto Montellano and Fullana military housing area have been constructed. In 1962 the bodies interred in the Henry Barracks cemetery were exhumed and transferred to the National Cemetery located in Bayamon Puerto Rico. The temporary building in front of the Commissary (currently the Office of the Superintendent of Schools) has been destroyed.

During the time between 1965 when the Post (Henry Barracks) closed to 1967 when the University of Puerto Rico began operation in the north part of the former Post, there were several activities of significance in the acreage comprising Henry Barracks69 (Figure 14).

8. Re-Establishment of Henry Barracks to Civilian Use

In January of 1965, Don Luis Muñoz Marin, the former governor, introduced a young

American by the name of Peter Pond to twelve young leaders in Cayey70 and challenged them to develop a program that would keep the Youth of Puerto Rico civically occupied using the deserted ground of Henry Barracks. La YMCA Cuerpos de Paz de Puerto Rico was Rev. Peter L. Pond’s conduit to programs for children that would assure inclusion, literacy, and foster well-being71. The report from this meeting as reported in El Mundo went like this: “the group meet with Governor Munoz Marin and his wife to discuss the possibilities of the program” According to Dr Juan A. Nogueras, one of the attendees to the meeting it was more like “marching orders”. Don Luis wanted a program that fostered voluntarism, involved youth, and engaged the citizenry in community level projects.

The “program” became “ VESPRA―Cuerpos de Paz de Puerto Rico”. It would operate initially from the grounds of old Henry Barracks, now the University of Puerto Rico in Cayey. With funds from the Rockefeller Foundation and later the Office of Economic Opportunities, and using “creative problem solving” community members, university students, teachers, and young professionals would engage in a volunteers movement that fostered literacy, public health projects at the “barrio level”, and would bring together youths into summer camps. The Fundación de Desarrollo Comunal took over a housing area in the north-eastern part of former Henry Barracks, the objective was to train personnel that would volunteer in the Federal Community Development Agency72. By 1970, the Foundation for Community Development reported to its funding source that it had been successful in meeting its objectives. The most important achievement was the Poor People’s Convention at the University of Puerto Rico in 196873.

A third program of great impact to the community and the region was the Encampment for Citizenship 196674. The program was initiated by the New York Ethical Society, the State Department of the United States, and former Governor Muñoz Marin. The objective was to bring Youth from diverse parts of the World and help them understand the concept of democracy in action. The summer of 1966 saw the greatest flow of ideas and intellectuals in what is now the center of the UPR-Cayey campus.

9. Summary

This paper presented the evolution of a place called Henry Barracks, Cayey from the Spanish rule and the outpost in Cayey, to the occupation of the only segregated Spanish- speaking Regiment in the United States Army, provided a historical overview of the role of the Henry Barracks Military Reservation in the economic development of the town of Cayey from 1898 to 1967 and its re-establishment as public lands. The history of this land has not been preserved. The University should make an effort to document the historical sites in its campus, and explain the impact of the former military installation in the economic and cultural impact in the region. At the very least the municipality of Cayey and the University of Puerto Rico should acknowledge with a historical marker the presence of the Spanish Encampment, and the visit of a sitting president of the United States (President Roosevelt) in 1906.
