In March 1988, Noriega's forces resisted an attempted coup against the government of Panama. As relations continued to deteriorate, Noriega appeared to shift his Cold War allegiance towards the Soviet bloc, soliciting and receiving military aid from Cuba, Nicaragua, and Libya. American military planners began preparing contingency plans to invade Panama.
The military incursion into Panama began on 20 December 1989, at 1:00 a.m. local time. The operation involved 27,684 U.S. troops and over 300 aircraft. These aircraft were deployed against the 16,000 members of the PDF.
The Raid at Renacer Prison was an attack on the El Renacer prison in Gamboa, Panama, by units of the 82nd Airborne Division of the US Army on 20 December 1989, during the United States invasion of Panama. During the raid the U.S. military was able to free the sixty-four prisoners held in the detention facility.
Noriega remained at large for several days, but realizing he had few options in the face of a massive manhunt and a $1 million reward for his capture, he obtained refuge in the Vatican diplomatic mission in Panama City. The U.S. military's psychological pressure on him and diplomatic pressure on the Vatican mission, Noriega finally surrendered to the U.S. military on 3 January 1990. He was immediately put on an MC-130E Combat Talon I aircraft and flown to the U.S.
