Attacks on U-518 during this patrol

2 Nov 1942
While entering the Gulf of St. Lawrence via the Cabot Strait, U-518 was depth-charged by a radar-equipped Canadian aircraft, but escaped unharmed. (Sources: Blair, vol 2, page 50.)

21 Nov 1942
04.26 hrs, approx 200 miles (322km) SE of Sydney, Nova Scotia: following a successful attack on convoy ON 145, U-518 was forced to dive when taken under fire by several ships in bright moonlight.

HMCS Buctouche made for the tracer fire, obtained an Asdic contact at 04.42 hrs and carried out an immediate attack with four depth charges set at 100 ft (30m). A whistle effect was heard afterwards, but as the contact had been lost and classified as non-sub, the escort rejoined the convoy.

The depth charges caused no damage, but unknown to the crew, U-518 was in serious trouble, because the mounting of the heating plug in the third torpedo tube had broken loose, causing uncontrollable flooding of the bow torpedo room from a thick jet of water, as the bow cap could not be closed. At 05.18 hrs, the boat was forced to surface, and escaped undetected to the north. It took almost three hours to pump the compartment out, and U-518 was forced to return to base because the damage left her unfit for combat. (Sources: ADM 199/1268)
