28 October, 1962

An 11,000-man 5th Marine Expeditionary Brigade left Camp Pendleton by sea for the Caribbean during the Cuban Missile Crisis. One week earlier, the entire 189,000-man Marine Corps had been put on alert and elements of the 1st and 2d Marine Divisions were sent to Guantanamo Bay to reinforce the defenders of the U.S. Naval Base. Other 2d Division units and squadrons from five Marine Aircraft Groups were deployed at Key West, Florida, or in Caribbean waters during the Cuban crisis.
