21. Port Stanley was surrounded with heavily fortified positions
The hills which surrounded Port Stanley were heavily defended. The Argentines were subjected to aerial and naval bombardment as the ground troops maneuvered into position. On June 11, the British launched their attacks on Argentine positions, striking at night. Argentine resistance was strong, though British troops advanced steadily, though attacks led to several “friendly fire” incidents as they pressed forward. On the morning of June 12, as the ground fighting continued, Argentine technicians used an improvised launcher to damage yet another British destroyer, HMS Glamorgan. The launcher had been developed and the missile reprogrammed in Argentina and delivered to Port Stanley by the nightly C-130 supply mission.
The Argentines had three available Exocet missiles, the first of which failed to launch. The second failed to lock onto the target and fell harmlessly to the sea. The third found the target, hit the ship near the stern, and penetrated into the hangar deck, where it exploded. It destroyed the ship’s helicopter in the hangar and started a massive fire. Fourteen crew were killed by the explosion and fire. It was the last Exocet to strike a British ship during the war. The crew was able to contain, and then extinguish the fire and the ship was underway, partially operational, later in the morning. Glamorgan returned to Britain after the war and underwent extensive repair and refit in Portsmouth.
