Porto Rican Regiment, 1917

The War Department authorized the creation of the 94th Infantry Division to be composed of four Porto Rican regiments.[1] The 94th Division would consist of four regiments 373, 374, 375, 376, the first two were assigned to the Tactical Brigade 187 while the 375-Colored, and the projected 376 were to form part of Tactical Brigade 188. A Home Guard “Guardia de la Patria” was also established to take over defense of the island in the unlikely case the Porto Rican division was sent overseas.

El Diluvio, a local publication very critical of island Governor Yager took special interest in the 375 Porto Rican Colored Regiment (94th Division) and wrote a series of articles detailing their training and progress. An editorial asserted that those soldiers were not “the less intelligent, nor the less smart, neither the ones less disposed to learn and ready themselves to defend with honor the name of Puerto Rico.” Instead, “… the more apt, humble and the most attentive of the recruits are those of the 375.” The editorial also mentioned that “the boys of the 375 will one day respond to the call of arms with the same unconditional bravery and tenacity shown by the colonial French troops and the brave Black soldiers of America.”[2]

Though unconvinced of their value as first line combat troops, the War Department believed that mobilizing Puerto Ricans would prove useful. These soldiers could relieve White Continental American soldiers from non-combat assignments freeing them for combat duty, while inspiring loyalty among the population of the island. The political and economic value of mobilizing as many Puerto Ricans as possible was well understood by the War Department. In December of 1918, Frank McIntire, Chief of the Bureau of Insular Affairs, wrote a memorandum to the Chief of War Plans Division informing him of the political, economic, and social benefits of mobilizing Puerto Rico’s, “…large surplus population, that is, a population for who in the present there is no continuous employment.”[3] After making clear that his views were not of a military nature, McIntire reported that the men who had gone through military training on the island, “…have been very much improved, physically and otherwise, and are better off for having had it and to that extent are of greater economic value.”


Freeing “White” Troops to do the Real Fighting

  • Role of Puerto Rican troops to be subordinated to labor lest their equal participation undermine the rationale behind imperial expansion.
  • Frank McIntire, Chief of the Bureau of Insular Affairs, reminded Yager that training in the U.S. would “make them [Puerto Ricans] better men on returning to Porto Rico, physically and otherwise, this, even though they should not go abroad at all for service.”
  • The war ended before the Porto Rican Division finished its training in Camp Las Casas.


The Porto Rican Regiment Goes Abroad

On July 1, 1908, under authority of an Act of Congress approved on May 27th, the Puerto Rico United States Volunteers became officially part of the regular army and was named the Porto Rico Regiment of Infantry U.S.A.

During World War I, the Porto Rican Regiment saw its role extended to include the defense of the Panama Canal. The possibility of a German attack on this facility, however, was practically non-existent. In theory, Mexico could pose a threat to the canal, but it rejected German overtures to join the Central Powers. The Porto Rico Regiment’s role during the World War I was that of freeing white American units for the Western Front. No one was going to attack the canal.
