They surfaced in a squall. Rain lashed the bridge like shrapnel. Through the grey curtain, the U-571 lay low in the water, her deck awash, her conning tower a shattered metal tooth. No lights. No movement. But the screws Tyler’s sonar man heard were real—two German destroyers, now a dark smudge on the horizon.

Despite some historical inaccuracies, "U-571" received generally positive reviews from critics and audiences. The film grossed over $30 million worldwide and was praised for its tense action sequences, good performances, and convincing depiction of life on a submarine.

On June 22, 1944, the USS Haddo located U-571 and engaged it in battle. After a prolonged fight, the U-boat was forced to surface, and a team of American sailors, led by Murphy, boarded the vessel and took control of it. The German crew was taken prisoner, and the Americans set about trying to learn as much as they could about the U-boat's operations and technology.
