Biography

Early Life
Calixto Lopez Piñero was born in Juncos, Puerto Rico, on October 19, 1924. His mother was Herminia Piñero and his father was Francisco López. Calixto grew up as the eldest of five children, four sons and one daughter. When Herminia died, Francisco remarried Concepcion Ruiz, and they had three daughters. 

Francisco worked for the railroad as the head of the station in Isabela, Puerto Rico. He instilled in Calixto a sense of discipline that would guide him throughout a life shaped by hard work and determination.

Homefront
Daily life in Isabela was shaped by poverty but also a strong sense of community and simplicity. People mostly ate rice, beans, soup, and bread, with meat being a rarity. Music and dance were key forms of entertainment, with pasodobles and romantic boleros heard over radios during parrandas. Religion—mostly Catholicism—was deeply ingrained in daily life, though churches were few. Education was limited; schools were small, poorly resourced, and split into short morning or afternoon sessions. Despite economic hardship, many remember the era as peaceful, with less crime and violence, and a lifestyle centered on family, resilience, and shared joys in modest surroundings.

In 1950, three major events impacted Puerto Rico. First, the U.S. Congress passed Law 600, which began the process of transforming the island to self-government through a new Constitution. Second, the Nationalist Party spearheaded a violent rebellion (which was quickly put down). And third, the outbreak of the Korean War led to the mobilization of thousands of young Puerto Rican men to fight communism 10,000 miles from home. López Piñero soon joined them.

Military Experience
The Borinqueneers occupy a unique spot in both the history of the military and in the history of Puerto Rico. Starting out as a volunteer regiment in the colonial period, they developed into the Army’s only all-Spanish unit, serving together in both world wars. 

Caxlito López Piñero answered the call to serve his country not once, but multiple times. He first enlisted in the U.S. Army in 1944 during World War II. He was honorably discharged in 1946, only to re-enlist shortly after. He was assigned to Company D of the 65th Infantry Regiment and stationed in Puerto Rico.

On March 11, 1948, López Piñero married Asisla Gonzalez Gutierrez in Isabela, Puerto Rico. They raised three children, Wilma, Calixto, and Doris.

In 1949, López Piñero participated in Operation Portrex (also known as the “Puerto Rican Exercise”). In this exercise, the 65th Infantry Regiment served as the “defenders” of the island of Vieques, and unexpectedly defeated the “attackers” from the 3rd Infantry Division. Their success caught the attention of military commanders.

When the conflict broke out in Korea, the military needed well-prepared units. The 65th Infantry Regiment deployed from San Juan on August 26, 1950, as one of the earliest units to join the fighting.  As the Puerto Rican troops crossed the Pacific, they held a contest to select their new name. Upon setting foot on the Korean peninsula they were known as the “Borinqueneers.” The name is a reference to “Borinquen,” the name the Taino called the island. The regiment was placed under the command of the 3rd Infantry Division. Members of the 65th Infantry Regiment fought side-by-side in Korea with soldiers they “defeated” in Operation Portrex.

In Korea, the Borinqueneers distinguished themselves. They entered combat in the Pusan Perimeter and helped repel the North Korean advance, then participated in operations with the U.S. Tenth Corps during the drive into North Korea. They served valiantly, covering the retreat of the first Marine Division from Chosin Reservoir, and were the last unit off the beach during the evacuation of Hungnam in December 1950. 

Just after the retreat, López Piñero’s tour ended. Instead of returning home, he re-enlisted and continued serving alongside his countrymen in combat for another ten months. They took part in operations to retake Seoul and advanced to the Imjin River. They engaged in significant battles, including the Soyang River area and Chorwon Valley, where they worked to secure strategic locations. López Piñero’s final months in battle were spent performing operations in the critical Iron Triangle region just north of the 38th parallel. 

López Piñero shipped home in November 1950. For his service, he received the Korean Campaign Ribbon with four bronze battle stars, the World War II Victory Medal, and the Combat Infantryman Badge, along with other honors. The brave service of the Borinqueneers earned the praise of military commanders, and made them heroes back home. 

After his time in Korea, López Piñero transitioned to the U.S. Air Force, where he served as a supply sergeant at Ramey Air Force Base in Aguadilla, Puerto Rico, and repeatedly received high praise on his evaluations. He received an honorable discharge in 1966, leaving behind a legacy of perseverance and excellence in his military career.

Veteran Experience
In his hometown of Isabela, Puerto Rico, López Piñero was a pillar of his community. A devoted family man, he and his wife Asisla Gonzalez raised three children, two daughters, and a son, instilling in them the same values of kindness and service that defined his life. He was a loving grandfather to six grandchildren. He was deeply involved in his church, the San Antonio Parish in Isabela, and was an active member of the Lions Club, where his leadership and dedication to community service left a lasting impact.

Commemoration
On November 15, 1999, Calixto López Piñero passed away, leaving behind a legacy of love, service, and faith. Today, we honor his memory and express our gratitude for the example he set. His story is a testament to the quiet heroism that shapes the lives of so many Veterans, a legacy we must never forget.

The 65th Infantry Regiment was awarded the Congressional Gold Medal in 2013.
