World War II veterans have gathered in Chicago to mark the 70th anniversary of their capture of a German submarine.

The U-505 submarine has been on display at the Museum of Science and Industry. The veterans who captured the 252-foot vessel have been meeting throughout the years at the museum. But museum officials say the veterans have decided Wednesday will be their last meeting because their numbers are dwindling.

The U-505 is the only German submarine that the U.S. Navy captured during the war and one of five left in the world. Navy Captain Daniel Gallery of Chicago led the group that captured the submarine.
