HMS Graph

About

HMS Graph (pennant number P715) was a German Type VIIC U-boat captured and recommissioned by the British Royal Navy during World War II. Commissioned as U-570 in Nazi Germany's Kriegsmarine in mid-1941, she was attacked and captured on her first patrol. She provided the Royal Navy and United States Navy with useful information about German submarines.

Refitted for use by the Allies, she carried out three combat patrols with a Royal Navy crew, becoming the only U-boat to see active service with both sides during the war. She was withdrawn from service in 1944 due to problems maintaining her. While being towed to the breakers for scrapping, she ran aground on the Isle of Islay, off the west coast of Scotland.

Some of the wreckage was removed as scrap but some remains to the present day.
