, 25 October 1983
H-hour for the invasion was set for 05:00 on 25 October 1983. U.S. troops deployed for Grenada by helicopter from
Grantley Adams International Airport on Barbados before daybreak. Nearly simultaneously, American paratroopers arrived directly by transport aircraft from bases in the eastern United States, and U.S. Marines were airlifted to the island from
USS Guam offshore. It was the largest American military action since the
Vietnam War.
Defending forces People's Revolutionary Army The invading forces encountered about 1,500 Grenadian soldiers of the
People's Revolutionary Army (PRA) manning defensive positions. The PRA troops were for the most part equipped with light weapons, mostly
Kalashnikov-pattern automatic rifles of Soviet
bloc origin and semiautomatic Czechoslovak
Vz. 52 carbines, along with smaller numbers of obsolete
SKS carbines and
PPSh-41 submachine guns. They had few heavy weapons and no modern air defense systems.
Cuban forces in Grenada The Cuban military presence in Grenada was more complex than initially evaluated by the U.S. Most of the Cuban civilian expatriates present were also military reservists. He later stated that he issued small arms and ammunition to the construction workers for the purpose of self-defense during the invasion, which may have further blurred the line between their status as civilians and combatants. They were also expressly forbidden to surrender to U.S. military forces if approached. The regular Cuban military personnel on the island were serving as advisers to the PRA at the time.
Bob Woodward wrote in
Veil that captured "military advisors" from socialist countries, including Cuba, were actually accredited diplomats and their dependents. He claimed that none of them took any actual part in the fighting. The U.S. government asserted that most of the supposed Cuban civilian technicians on Grenada were in fact military personnel, including special forces and combat engineers. A summary of the Cuban presence in
The Engineer, the official periodical of the
U.S. Army Engineer School, noted that "resistance from these well-armed military and paramilitary forces belied claims that they were simply construction crews."
Navy SEAL reconnaissance missions U.S. Special Operations Forces were deployed to Grenada beginning on 23 October, before the 25 October invasion. Navy SEALs from
SEAL Team 6 and Air Force combat controllers were air-dropped at sea to perform a reconnaissance mission on Point Salines. The helicopter drop went wrong; four SEALs were lost at sea and their bodies never recovered, causing most people to suspect they had drowned. The four SEALs were Machinist Mate 1st Class Kenneth J. Butcher, Quartermaster 1st Class Kevin E. Lundberg, Hull Technician 1st Class Stephen L. Morris, and Senior Chief Engineman Robert R. Schamberger. In an interview conducted by Bill Salisbury and published on 4 October 1990, Kenneth Butcher's widow claimed that she had gone to Grenada hoping that her husband had survived. She said, "There was this fisherman who said he saw four guys in wetsuits come out of the water, and then two days later he saw four bodies being thrown into the water. So we would like to think they made it, 'cause there was a boat smashed up on the beach. We would like to think the four of them got in that boat, made it to shore, got someplace, and were captured. And they're, you know, gonna come back." The SEAL and Air Force survivors continued their mission, but their boats flooded while evading a patrol boat, causing the mission to be aborted. Another SEAL mission on 24 October was also unsuccessful, due to harsh weather, resulting in little intelligence being gathered in advance of the impending intervention.
Air assault on Point Salines light machine gun and other weapons seized during Operation Urgent Fury, Alpha and Bravo companies of the 1st Battalion of the
75th Ranger Regiment embarked on
C-130s at
Hunter Army Airfield at midnight on 25 October to perform an air assault landing on Point Salines Airport, intending to land at the airport and then disembark. The Rangers had to switch abruptly to a parachute landing when they learned mid-flight that the runway was obstructed. The air drop began at 05:30 on 25 October in the face of moderate resistance from
ZU-23 anti-aircraft guns and several BTR-60
armored personnel carriers (APCs), which were knocked out by
M67 recoilless rifle fire.
AC-130 gunships provided support for the landing. Cuban construction vehicles were commandeered to help clear the airfield, and one even used to provide mobile cover for the Rangers as they moved to seize the heights surrounding the airfield. The Rangers cleared the airstrip of obstructions by 10:00, and transport planes were able to land and unload additional reinforcements, including
M151 Jeeps and members of the
Caribbean Peace Force assigned to guard the perimeter and detainees. Starting at 14:00, units began landing at Point Salines from the
82nd Airborne Division under
Edward Trobaugh, including battalions of the
325th Infantry Regiment. At 15:30, three BTR-60s of the Grenadian Army Motorized Company counter-attacked, but the Americans repelled them with recoilless rifles and an AC-130.
Raid on Radio Free Grenada UH-60 Blackhawk helicopters delivered
SEAL Team 6 operators in the early morning of 25 October to Radio Free Grenada with the purpose of using the radio station for
psychological operations. They swam toward the open sea, and were picked up several hours later after being spotted by a reconnaissance plane. The raid on Richmond Hill Prison lacked vital intelligence, leaving the attackers unaware of the presence of several anti-aircraft guns and steep hilly terrain that left no room for helicopter landings. Anti-aircraft fire wounded passengers and crew and forced one UH-60 helicopter to
crash land, causing another helicopter to land next to it to protect the survivors. One pilot was killed, and the Delta Force operators had to be relieved by a Navy
Sea King helicopter. The raid on Fort Rupert, however, was successful in capturing several leaders of the People's Revolutionary Government.
Mission to rescue Governor-General Scoon The last major special operation was a mission to rescue Governor-General Scoon from his mansion in
Saint George, Grenada. The mission departed late at 05:30 on 25 October from Barbados, resulting in the Grenadian forces being already aware of the invasion and they guarded Scoon closely. The SEAL team entered the mansion without opposition, but
BTR-60 armored personnel carriers counter-attacked and trapped the SEALs and governor inside.
AC-130 gunships,
A-7 Corsair strike planes, and
AH-1 Cobra attack helicopters were called in to support the besieged SEALs, but they remained trapped for the next 24 hours. At 19:00 on 25 October, 250 Marines from G Company of the
2nd Battalion, 8th Marine Regiment landed at Grand Mal Bay equipped with
amphibious assault vehicles and four
M60 Patton tanks; they relieved the Navy SEALs the following morning, allowing Governor Scoon, his wife, and nine aides to be safely evacuated at 10:00 that day. The Marine tank crews continued advancing in the face of sporadic resistance, knocking out a BRDM-2 armored car. G Company subsequently defeated and overwhelmed the Grenadian defenders at Fort Frederick.
Airstrikes Navy
A-7 Corsairs and Marine
AH-1 Cobra attack helicopters made airstrikes against Fort Rupert and Fort Frederick. An A-7 raid on Fort Frederick targeting anti-aircraft guns hit a nearby mental hospital, killing 18 civilians. Two Marine AH-1T Cobras and a UH-60 Blackhawk were shot down in a raid against Fort Frederick, resulting in five casualties. ==Second day of the invasion==
