Spanish colonial period (1510–1898)

The PRNG claims direct descent from the Puerto Rican militias that were founded after the Spanish Empire granted the island a governor and general captain.^[10] Its first large conflict emerged from the response to the Spanish–Taíno War of San Juan–Borikén, only years after the arrival of Juan Ponce de León and before the totality of Puerto Rico was under Spanish sovereignty.^[11] The Taínos of Borikén, led by Agüeybaná II were forced into labor and their territory threatened by the Spanish expansionism in the region, consequently deciding to begin a counteroffensive by killing Cristóbal de Sotomayor, the leader of a settlement built in southern Puerto Rico.^[11] Lacking a formal structure during the initial stages of the colonization, the Spanish settlers were forced to adopt a military initiative and organize these militias, while also continuing their main jobs, giving rise to the first civilian reserves.^[11] Additional native attacks took place in 1514 and 1520 (by which point they had been driven into exile in the Lesser Antilles).^[12] During this decade, French buccaneers would also become a threat, attacking the archipelago in 1528, only for more exiled Taínos to attack the following year.^[12] Hostile adversaries would make a single incursion during the following decade, one was an attack attributed to island Caribs (in 1556) and the other a French attack, the only reported during the following thirty years.^[12] However, the 1570s saw a surge in activity, with buccaneers attacking in 1570 and 1576 and the natives in 1573.^[12]

Puerto Rico was considered a strong strategic point by the Spanish Empire due to its location as the last bastion before taking the transatlantic voyage to Europe, and due to this fortification of its ports began during the second half of the 16th century.^[13] The first major attack faced by the militias was led by Francis Drake in 1595, leading thousands of men in the Battle of San Juan but being repelled.^[12] In 1598, George Clifford, 3rd Earl of Cumberland managed to take the city in the second Battle of San Juan after battling his way through the local militias, but was forced to leave two months later due to an epidemic.^[12] Despite this setback, the local militias earned enough of a reputation for the next governor, Alonso de Mercado, to reportedly send back most of the soldiers that accompanied him in his voyage and rely on them for defensive purposes.^[14] The main fortress of San Juan Bay, El Morro, was finished by 1608 and additional fortifications such as San Cristóbal soon followed.^[13] The next major engagement took part 27 years later, when Nerherlands lead another failed invasion in the third Battle of San Juan.^[12] The militias would also participate in military incursions in other adjacent islands, including some that are now part of the Puerto Rican archipelago.^[12]

In 1765, Marshall Alejandro O'Reilly who would later become known as "El Padre de las Milicias", reorganized the militias and created a group that was disciplined enough to fight in regular combat at the Anglo-Spanish War and be commended by the crown.^[15] In 1797, the British attempted another invasion, this time led by Ralph Abercrombie, but were defeated by a force that heavily depended on the local militias in the fourth Battle of San Juan.^[3] In 1868, amidst a growing pro-independence in the population that eventually lead to the Grito de Lares, the Spanish government decided to replace the mostly Puerto Rican quorum of the militias with an Institute of Volunteers that was completely composed of Spanish-born citizens.^[16] During the decades that followed, the loss of several former colonies and of influence in the continent affected the maintenance of the local military installations and of the force, leading to an ill-prepared force with which to face the Hispano-American War.^[16]

Early American colonial period (1898–1938)

In 1906, a group of men led by Commissioner of Interior Lawrence H. Grahame decided that there was a need to create a national guard that mirrored those in the states in order to replace the militias.^[17] Companies were created in Yauco, Juana Díaz, Peñuelas, Ponce and San Juan.^[17] This entity was initially dependent on volunteers that were trained in El Morro, none of which received a salary.^[18] However, the colonial legislature failed to approve a project that was meant to authorize the organization and seek funding, causing the initiative to be halted.^[18]

Cadet Luis R. Esteves, 1915

With the onset of World War I and the mobilization of the 373th, 374th and 375th regiments of the Regular Army, the need for a local military force became evident as some 20,000 men were trained in Camp Las Casas.^[16] As soon as the war concluded, a local officer, Luis Raúl Estevez, inquired colonial governor Arthur Yager about reactivating the national guard, an initiative that gained the support of the official and the colonial legislature.^[19]

On July 19, 1919, Congress passed a law approving the budget for the following year to meet the requirements of the National Defense Act of 1916.^[20] Adjutant General John Wilson was given command over the nascent organization.^[21] On July 19, 1919, the United States Department of War informed Yager about the administration's intention of supporting a local reserve pursuant to the statutes of this law to create a permanent national guard that was capable of assisting the other branches of the military or working independently.^[22] The entity resumed operation and was meant to receive an infantry brigade, with artillery, cavalry, engineering and specialized troops.^[22] Esteves became the first commander of the current interaction of the PRNG.^[19] Company A was organized under Cpt. Luis Irizarry on November 23, 1919.^[23] The unit was trained in terrains and buildings that were lent by Carmelo Alemar of the Agricultural Experimental Station.^[24] Company B was organized on February 1, 1920, and was separated a week later in two companies stationed in San Sebastián (Company M) and Lares (Company L) which were later formally organized.^[25] On February 7, 1920, several new companies were organized, including Company E in Ponce, Company G in Yauco.^[26] On February 25, 1920, the First Regiment Puerto Rico Infantry was provisionally organized under Mayor Luis Esteves, receiving Companies A, B, M, L, E, G and Headquarters.^[27]

Company F was organized on March 7, 1920, in Peñuelas.^[28] The following week, Company I was organized at Arecibo.^[29] On April 13, 1920, Company C was organized in Cabo Rojo.^[30] On April 25, 1920, Company H was organized at Sabana Grande.^[31]

On April 30, 1920, the First Regiment received command of a number of headquarters at San Juan, Mayagüez and Sabana Grande.^[32] On May 9, 1920, Company D was organized at San Germán.^[33] Towards the month's end, Company K was organized at Bayamón.^[34] On May 30, 1920, the designation of Company B was reassigned to a company in Maricao.^[35] That same day, Troop A of the First Squadron P.R. Cavalry was organized in Mayagüez.^[36]

The First Infantry Regiment was formally recognized on June 2, 1920, before becoming the 295th Infantry Regiment two years later.^[19] With Esteves as its senior instructor, The regiment is symbolically considered the older within the structure of the US national guards due to its claim.^[37] On June 14, 1920, the First Infantry Medical Detachment was organized in Mayagüez.^[38] On June 17, 1923, the 296th was separated as a splinter, with its first Battalion winning recognition for best company in the national guard twice.^[19] The First Regiment's First Headquarters Company was organized in Bayamón three days later.^[39] Later that week, the first PRNG band was organized at Mayagüez.^[40] The First Regiment's Machine Gun Company was organized at San Juan on September 19, 1920.^[41] More than two months later, its Supply Company was organized at San Juan.^[42] The first annual exercises began on December 6, 1920, at Salinas, during the following years this camp would be moved throughout the camps.^[43]

In the 1920s, several groups dedicated to target shooting were scattered throughout Puerto Rico, with the PRNG deciding to organize competitions.^[44] On November 24, 1930, personnel from the entity founded the Ponce Rifle and Sporting Club, later affiliating itself with the National Rifle Association.^[45] The PRNG itself would promote these events, forming the Puerto Rico National Guard Shooting Club presided by Salvador Roig.^[46]

The national guard was mobilized after the passing of hurricane San Felipe in 1928 and San Ciprián in 1932.^[47] During these disasters, they were assigned civil assistance.^[48] Similar interventions took place in the Dominican Republic and Haiti.^[49] In 1933, the 296th First Battalion won the Harrison Cup.^[50]

On May 3, colonial governor Winship argued for a light artillery unit.^[51] On March 16, 1936, the PRNG underwent a reorganization.^[52] In February 1934, Gen. George Leach, who oversaw Company A of the 295th, visited Puerto Rico and was surprised to see that the bayonets had been repaired motu proprio with local resources and their discipline, promoting him to pronounce during a speech that he had "inspected the national guards of the 48 states" and not seen one better prepared than the PRNG, going to the extent that if the president asked which was the best regiment for defense, it would be the 295th.^[53] The 296th remained under the supervision of the 295th until June 1, 1936, when it was designated as a regiment under Col. Luis Irizarry.^[52] In 1937, the 296th first Battalion was reassigned to the 295th as Company A.^[50] In 1938, the PRNG joined the 65th Infantry Regiment and participated in exercises supervised by Gen. Frank Ross McKoy.^[54] On July 25, 1938, Irizarry was killed during an assassination attempt against colonial governor Winship in one of several confrontations between the government and the Puerto Rican Nationalist Party following the events of the Ponce massacre.^[52] Col. José Enrique Colom took over the 296th Regiment.^[55]

In 1938, the 295th, 65th and 296th Regiments and other personnel from the PRNG joined the Regular Army in a number of military exercises also involving the Navy.^[56] The three regiments formed a brigade that was led by brigadier general Walter Short and was given jurisdiction over Puerto Rico in case of military action.^[56] The following two years, annual training was held in Arecibo and Tortuguero in anticipation to the impending activation in the newly declared World War II.^[55] Wilson died in December 1938, and months later Luis Raúl Esteves was given command of the PRNG.^[57] On August 3, 1939, the national guard paid homage to the colonel of the 296th, José Colom, who was serving as interim governor of Puerto Rico, with a mass march (the first of this kind held under the colonial administration) to commemorate Governor's Day.^[58] In turn, Colom handed several recognitions to the companies and soldiers that distinguished themselves during the year.^[59]

On January 8, 1940, an emergency camp was held and a training exercise where an invasion of the northern coast of Puerto Rico was being invaded, in particular the municipalities of Arecibo and Vega Baja, and the 295th and 296th were tasked with repelling it.^[60] Both were placed in charge of solving a tactical exercise, code named MUSKETRY, which involved a sudden appearance by a hostile force.^[61] In March 1940, a new military code for Puerto Rico was presented to the colonial legislature along other initiatives related to the PRNG.^[62] The final annual camp prior to activation in World War II was the longest yet, lasting three weeks.^[63] On May 19, 1940, the PRNG was mobilized to attend the flooding caused by Rivera Portugués and Bucaná in Ponce.^[64]

During this time, the PRNG underwent a reorganization that led to the transfer of guardsmen and units, as well as the creation of new units.^[65] In June 1940, the 162nd Battalion of Field Artillery was first organized, with its batteries (A through C) being assigned to San Juan, Río Piedras and Ponce.^[66] This same year, the 130th Engineering Regiment received authorization to organize its 1st Battalion, with its companies being assigned to San Juan, Mayagüez and Guayama.^[67] The 295th's Company A was reassigned as the 296th's Company K.^[50] This reorganization led to the ascension of several officers to accommodate the new units.^[68]

World War II and reorganization (1938–1950)

On October 15, 1940, the PRNG was activated pursuant to Executive Order 3551.^[69] A group of 1,359 belonging to 295th Infantry Regiment were assigned to Campamento Tortuguero in Vega Baja, Puerto Rico where training was under seen by Esteves under Col. Miguel A. Muñoz.^[69] The 296th had a force of 1,363 and joined the 295th at Tortuguero.^[70][71] The other units, which included those that received formal recognition on this date, were the 92nd Brigade (47 men), the 162nd Artillery Battalion (274 men), the 130th Engineering Battalion (193 men), the 253rd Artillery Battalion (175 men) and the 201st/123rd Artillery Battalion (323 men).^[70] Besides San Juan, the municipalities of Ponce, Mayagüez, Vega Baja, Manatí, Arecibo, Bayamón, Caguas, Fajardo, Humacao, Cayey, San Germán, Maricao, Cabo Rojo, Sabana Grande, Peñuelas, Yauco, Aibonito, Coamo, Juana Díaz, Río Piedras, Guayama and Aguadilla had personnel assigned to them.^{[72][73][74][75]} The 130th Regiment was placed under the Regular Army and trained by the 27th Combat Engineering Regiment at Tortuguero, where its Company A was charged with additional constructions.^[67]

On March 19, 1941, additional personnel was assigned to the 295th Regiment, and shortly afterwards it was moved to Salinas, Puerto Rico, for further training.^[69] On August 12, 1941, Colom left the 296th Regiment and was replaced by Col. Antulio Segarra.^[76] The 130th and 27th Engineering were reorganized in a Combat Engineering Regiment in charge of Lt. Col. Sylvester Nordner and continued working on the infrastructure of the local bases.^[77]

Engineers of the 65th Infantry Regiment in Korea

On December 7, 1941, the PRNG was assigned to surveillance and monitoring operations throughout Puerto Rico.^[69] After more than a year performing this task, the 295th Infantry Regiment was separated in two battalions and reassigned to operate in Aruba and Curazao, while the rest of the personnel was placed on detachments and sent in operations that took place in Suriname, Trinidad, Jamaica and Cuba.^[78]

On January 7, 1943, the 65th Infantry Regiment was assigned to Panama led by Commander Salvador Roig, with 300 men being transferred from the 296th to complement its force.^[76] The remainder of that regiment remained at Camp O'Reilly in Gurabo.^[76] On October 30, 1943, Col. Eduardo Andini took over the 296th Regiment.^[76] In December 1943 the 295th Infantry Regiment was reorganized in Puerto Rico and the following month began replacement operations in Campanento Tortuguero.^[78] That same month, Col. Andrés López Antongiorgi took over the 296th Regiment and its battalions were systematically transported to Panama where it took over the work previously done by the 65th, which was reassigned to North Africa.^[76] The regiment also provided 400 men and a Cannon Company to the parting unit.^[76] The 266th Regiment was given the task of guarding the Panama Canal Zone, both in the Atlantic and Pacific coasts, and participated in missions in Peru, Galapagos and Ecuador under Col. Francisco Parra Toro.^[76] It served in the Mobile Forces, in jungle training and performed before visiting Latin American officials.^[79]

Three months later, the 295th Regiment began training at Camp O'Reilly and was later translated to Losey Field.^[78] On May 13, 1943, the 162nd Battalion traveled to Panama, where it replaced the 2nd Field Artillery Battalion and was assigned the medical detachment two months later.^[80] During the summer, the 295th was assigned to Panama, where replaced the 296th Regiment in the Mobile Force and surveillance operations under Col.

In March 1946, they were returned to Puerto Rico, where it was demobilized shortly after arrival.^[82] On May 6, 1946, the 162nd was demobilized and reorganized under Lt. Col. Jaime Fullana, with its batteries being granted recognition between 1947 and 1948.^[81]

The conclusion of the war lead to the license and honorable discharge of several members of the PRNG, who wanted to continue their civilian lives.^[82] during the summer of 1946, Esteves reorganized the 295th and 296th Infantry Regiments.^[82] The Department of War issued a plan where the PRNG would be reorganized into headquarters, two units 295th and 296th, an anti-air group, and numerous battalions, detachments, companies and other specialty groups at a cost of 2.5 million per year.^[83] Secretary Patterson, who was once a member of his local national guard, felt an urgency to reorganize the civil guard as soon as possible.^[84] In the recruitment initiative that followed, the PRNG would finish second among the 51 national guards affiliated to the USNG, only behind Wyoming, surpassing pre-established goals for a 204% of the total.^[85] The most successful recruiter, Arturo Romañat, received a commendation and traveled to Washington where he met several high-ranking officials.^[86]

The 296th was placed in charge of Col. Juan Cordero.^[82] Company Headquarters for the first and second natal lions were located in Mayagüez and Ponce, with Lieutenant Colonels Rafael Sepúlveda, Manuel Nazario and Invan Domínguez.^[87] The 296th's Company A (based in San Germán) became the first unit to complete quorum among all national guards affiliated to the United States following the war, and won the Eisenhower Trophy in consecutive years.^[88] Between October and December 1946, other companies were scattered throughout Puerto Rico.^[88]

On September 15, 1946, the 295th Infantry Regiment was taken over by Col. Wilson Colberg.^[89] This coincided with the establishment of Company Headquarters led by Cpt. Ramón Cantero.^[89] The 295th held its first Annual Training under this new regime in August.^[89] On November 3, 1946, the first set of commissions were awarded to the new PRNG.^[90] Black men were not allowed to enlist in the PRNG until December 3, 1946, when colonial governor Jesús T.

Troops of the Puerto Rico National Guard, commanded by Puerto Rico Adjutant General Major General Luis R. Esteves and under the orders of Governor Luis Muñoz Marín, during the occupation of Jayuya

During the following years, the dichotomy between the government of Luis Muñoz Marín and the Nationalist Party was widened over the Commonwealth that was being negotiated in Congress. On October 30, 1950, these differences materialized in the Jayuya Uprising. The 295th Infantry Regiment was mobilized from the beginning of the insurrection until November 6, 1950.^[89] In the crossfire that took place at Utuado, Corporal José Rodríguez Alicea of H Unit in Arecibo was killed.^[89] The 296th's First Battalion was mobilized under Lt. Col. Rafael Sepúlveda, was moved to forts Brooke and Buchanan.^[101] This revolution was quelled after the Puerto Rico Air National Guard bombed the municipalities of Jayuya and Utuado, the first and so far only time that the United States military has bombed a locale under the jurisdiction of the federal government. Following the crossfire, the PRNG confiscated a flag of Puerto Rico that had been placed before the Jayuya Police Headquarters.^[103] For its participation in this conflict, the entity received letters of gratification from the Police of Puerto Rico and other organizations affiliated to the government such as the Puerto Rico Water Resources Authority.^[104] In turn, Esteves commended a number of officers for their coordination.^[105]

On September 14, 1952, the 296th's Headquarters Company was organized.^[109] In 1953, the 296th Annual Training was heavily affected by the moves to service.^[110] The PRNG also promoted assistance by awarding a golden cup to units with perfect assistance.^[111] Battery B of the 482nd was returned to the jurisdiction of Puerto Rico and received a recognition by the Army.^[112]

Cold War and governor assignments (1954–1991)

Brigadier Gen. Kenneth Sweany attended the summer training in July 1954, expressing satisfaction following the Governor's Day parade that culminated it.^[113] On November 19, 1954, the Regular Army formally returned the designation of 296th Regiment to the PRNG in an activity hosted by Muñoz Marín, this under new administrative personnel due to several former members remaining in active service.^[114] Detachments were then assigned to several municipalities.^[115] The Regiment was able to gather enough troops, but the officers were scarce due to active service and the Inactive Reserve.^[110] Other moves included the adoption of a fighting cock as new insignia and the establishment of a periodical.^[110] The efficiency of the personnel was gauged in shooting competitions, with the results being sent back to the USNG for comparison with other national guards.^[108] In 1955, a Commission of the House of Representatives supervised the PRNG's exercises to gauge the entity's efficiency.^[116] During the passing of Hurricane Santa Clara, the 296th's Company I provided support to the government.^[117] The 296th's Engineering Company 225 was tasked with the construction of a bridge.^[117]

The PRNG underwent another reorganization on February 15, 1959.^[117] The tank companies of the 295th and 296th Regiments were assigned to the first battalion in Ponce.^[117] Several pre-existing companies were reassigned into the creation of the new Group 65.^[118] Several other companies were reassigned new names and purpose, including the 162nd, 482nd and 123th Battalions.^[118] On February 15, 1959, the 296th was assigned to Mayagüez under Col.

On February 21, 1960, commemorated as National Guard Day, the 65th Infantry Regiment was transferred from the Regular Army to the PRNG, in an activity where Gen. Cesár Cordero handed the unit's colors to Col. Rafael Rodríguez.^[123] During this time, governor Luis Muñoz Marín took over the office of adjutant general.^[122] On September 5, 1960, the PRNG was activated to attend a series of building and bridge collapses caused by floods brought by the adjacent passing of Hurricane Donna, which lead to the deaths of 149 civilians.^[124] In December 1961, the PRNG was involved in the reception of John F. Kennedy during his visit to Puerto Rico.^[125]

Puerto Rico National Guardsmen in 2012

The Military Academy of the Puerto Rico National Guard was established on June 1, 1963, at Camp Tortuguero on an initiative of César Cordero.^[126] Its curriculum was equivalent to Fort Benning's and lasted for a year and 15 days, at which point graduates received their certification.^[127] The institution was subsequently moved to Henry Barracks in Cayey and from there to Campamento Santiago.^[126] On May 1, 1964, the PRNG underwent another reorganization, the second under Gen. Cordero.^[128] On March 20, 1966, Salvador Roig was placed in charge of the PRNG by Roberto Sánchez Vilella.^[129] The PRNG also engaged in other civil activities, such as cooperativism (several becoming involved with Cooperativa El Sentinela) and inter-agency softball tournaments.^[130][131]

In 1968 and 1969, Gen.
