A total of 121 Puerto Rican soldiers were among the 8,200 people from the United States Armed Forces listed as missing in action during the Korean War. This total does not include people of Puerto Rican descent who were born in the U.S. mainland. It was during the Korean War that Puerto Ricans suffered the most casualties as members of an all-Hispanic volunteer unit: the 65th Infantry Regiment. One of the problems the unit faced was the language difference; the common foot soldier spoke only Spanish, while the commanding officers were mostly English-speaking. The Battle of Outpost Kelly (illustration pictured) accounted for 73 of the men missing in action from the total of 121. Out of the 73 MIAs suffered by the regiment in the month of September, 50 of them occurred on the same day: September 18. All 121 men served within the ranks of the United States Army with the sole exception of Ramón Núñez-Juárez, who served in the Marines. Their names are inscribed in El Monumento de la Recordación located in San Juan, Puerto Rico. (Full list...)
