Setting the scene
The U.S. invaded Grenada on October 25, 1983, in Operation Urgent Fury, overthrowing a Marxist government in the Caribbean island nation. Grenada's Prime Minister Maurice Bishop had been killed on October 19 in a coup by hardliners. President Reagan, citing threats to 600 American medical students and a request from Caribbean neighbors, ordered the invasion. The operation involved 7,600 U.S. troops against 1,500 Grenadian and 700 Cuban soldiers and workers.
What happened
The invasion was militarily successful but chaotic—U.S. forces faced poor intelligence, incompatible radios, and friendly fire incidents. The fighting lasted three days, with 19 Americans, 45 Grenadians, and 25 Cubans killed. The U.S. rescued the medical students and captured Cuban construction workers building an airstrip the U.S. claimed was for Soviet military use.
Why it still matters
The invasion was condemned by the UN and Britain but popular in the U.S., boosting Reagan after the Beirut barracks bombing that killed 241 Marines two days earlier. It was the first major U.S. military operation since Vietnam and restored confidence in the military. Grenada established a democratic government. The invasion demonstrated Reagan's willingness to use force against communism in the Western Hemisphere and marked the beginning of the end of Cold War caution about intervention.
