In photos: A friendship between two soldiers on opposite sides saved lives during the invasion of Panama

Captain Amadis Jimenez (left) and Gen (Rt) Marc Cisneros remain close friends 30 years after they fought on opposing sides in the invasion of Panama.

Amadis Jimenez was promoted to captain a few days before the invasion of Panama. He took over his new command at the Coco Solo naval infantry base a few hours before the bombardment began. Seen here graduating as sub-lieutenant.

Gen Marc Cisneros had a distinguished 35-year military career and was the highest-ranking Hispanic military officer by the time he retired in 1996. He fought in the legendary Tet offensive in Vietnam in the late 1960s. But it’s his role in the 1989 invasion of Panama – and what he did with Jimenez - that he will be most remembered for, perhaps.

U.S. began shelling the Panamanian naval infantry base at Coco Solo at 11.20pm on December 19, 1989. It was the initial assault during Operation Just Cause and was one of the few bases where The Penagon sid U.S. forces encountered resistance, led by Panamanian Captain Amadis Jiménez.

During the invasion of Panama, Amadis Jiménez and Gen Marc are credited with convincing 75 percent of the Panamanian forces to surrender without a fight. "People describe Marc as having won the war with a telephone," said his former boss in Panama, Gen Fred Woerner. "He saw a way to accomplish the mission, and at the same time minimize the loss of life and destruction. He was the glue in Just Cause."

After being captured by US forces during the invasion of Panama, Captain Amadis Jiménez requested his phone book where he had the numbers of Noriega commanders at Panamanian bases throughout the country to help General Marc Cisneros convince them that they surrendered without further bloodshed.

Cisneros found the perfect partner in Jimenez. When he got wind that U.S. forces had captured a Panamanian officer his curiosity was piqued by word that the prisoner was married to an influential family tied to the political opposition.

After he surrendered to U.S. forces on Jan 3, 1990, Noriega was quickly put aboard a U.S. plane to be taken to stand trial in Miami on drug cgarges.

With Noriega in prison in the United States, and a new democratically-elected president, Guillermo Endara, installed in Panama, the focus of U.S. troops switched to reconstruction and “nation building.”

Cisneros only remained in Panama for six months after the invasion. Due to his testy relationship with General Thurman he requested a transfer. But his friendship with Jimenez lasts to this day.

The son of a mechanic brought up on the Texas border with Mexico, Gen Marc Cisneros he could have been drawn straight out of central casting. Tall, muscular and ruggedly handsome, he had looks that belied his 50 years.

Everyone in Panama knew who Gen Marc Cisneros was. He was practically a household name in Panama at the time due his ability to make plain-spoken radio interviews Spanish in which he frequently lambasted Noriega.

The Panama invasion force was put under the command of Gen Maxwell Thurman (left), stern, by-the-book officer with little or no combat experience, known universally as ‘Mad Max.’ Thurman (left) seen here pinning a decoration on Cisneros (right).

Thurman thought it was conventional warfare. He really didn’t like that Cisneros was the guy who knew what was going on,” said military historian Lawrence Yates. “Cisneros would talk about cultural awareness with his officers while Thurman went around in his military fatigues trying to impress everyone,” he added.

"You have earned your country's lasting gratitude," reads this signed photo of gen Marc Cisneros with President George H Bush. It hangs prominently in Cisneros's home office in Corpus Christi, Texas. Cisneros comes from a family with a history of public service. His great uncle, J.T. Canales, was a leading Texas Mexican-American political leader, who helped found the League of United Latin American Citizens (LULAC). After he retired from the military he was named president of Texas A&M University-Kingsville.
