The incident involving PT-109 and the Japanese destroyer Amagiri took place during World War II in the Pacific Theater, specifically near the Solomon Islands. PT-109 was part of a series of coastal patrols aimed at disrupting Japanese supply lines and gaining control of strategic waterways. The Motor Torpedo Boat was a small, fast vessel used effectively for hit-and-run tactics, relying on stealth and agility.

On the night of the collision, PT-109 was on a nighttime patrol when it was suddenly struck by Amagiri. The impact resulted in a catastrophic breach, leading to the sinking of the boat. Lieutenant John F. Kennedy, who would later become the 35th President of the United States, showcased immense bravery and leadership during the crisis. After the boat sank, he swam to nearby islands with several crew members, guiding them to safety and ensuring they could evade Japanese patrols.

The story of PT-109 and its crew soon became well-known not only for the daring rescue but also for Kennedy's effective command under fire. His actions during this incident highlighted his capacity to handle extreme stress, which would later shape his political career and public image. The event also underscored the dangers faced by PT boats during the war and their crucial role in naval operations in the Pacific.
