"Chatelain was so close to
U-505 that
depth charges would not sink fast enough to intercept the U-boat, and instead opened fire with a
hedgehog battery before passing the submarine and turning to make an attack with
depth charges.
[17] At around this time one of the aircraft sighted
U-505 and dived on it, firing into the water to mark the position while
Chatelain fired depth charges. Immediately after the detonation of the charges a large oil slick spread on the water and the fighter pilot overhead radioed, "You struck oil! Sub is surfacing!"
[21] Less than seven minutes after
Chatelain's first attack began, a badly damaged
U-505 surfaced less than 600 metres (700 yd) away.
[20] Chatelain immediately opened fire on U-505's decks with all available automatic weapons, while other ships of the task force and the two Wildcat fighters also opened fire.
[17] Wounded and believing that
U-505 was seriously damaged, the commanding officer of
U-505 ordered his crew to abandon ship — an order obeyed so promptly that
scuttling was not completed and the engines continued to run.
[17] With the engines still running and the rudder damaged by the detonation of the depth charges,
U-505 circled clockwise at approximately 7 knots (13 km/h). Seeing the U-boat turning toward him and believing it was preparing to attack, the commanding officer of
Chatelain ordered a single
torpedo fired at the submarine – however, the torpedo missed and passed ahead of the now-abandoned U-505.
