In great detacation to JFK

Military

In the spring of 1941, Kennedy volunteered for the U.S. Army, but was rejected, mainly because of his troublesome back. However, the U.S. Navy accepted him in September of that year. He participated in various commands in the Pacific Theater and earned the rank of lieutenant, commanding a patrol torpedo boat or PT boat.

On August 2, 1943, Kennedy's boat, the PT-109, was taking part in a night-time military raid near New Georgia (near the Solomon Islands) when it was rammed by a Japanese destroyer. Kennedy was thrown across the deck, injuring his already troubled back. Still, Kennedy somehow towed a wounded man three miles through the ocean, arriving on an island where his crew was subsequently rescued. Kennedy said that he blacked out for periods of time during the ordeal. For these actions, Kennedy received the Navy and Marine Corps Medal under the following citation:

:"For heroism the rescue of 3 men following the ramming and sinking of his motor torpedo boat while attempting a torpedo attack on a Japanese destroyer in the Solomon Islands area on the night of Aug 1-2, 1943. Lt. KENNEDY, Capt. of the boat, directed the rescue of the crew and personally rescued 3 men, one of whom was seriously injured. During the following 6 days, he succeeded in getting his crew ashore, and after swimming many hours attempting to secure aid and food, finally effected the rescue of the men. His courage, endurance and excellent leadership contributed to the saving of several lives and was in keeping with the highest traditions of the United States Naval Service."

Kennedy's other decorations of the Second World War include the Purple Heart, Asiatic-Pacific Campaign Medal, and the World War II Victory Medal. He was honorably discharged in early 1945, just a few months before the Japanese surrendered.
