Attacks on this boat

9 Oct 1940
On the morning of this day, U-103 sighted convoy SC-6. After a successful attack at 2200hrs the boat was depth charged by a convoy escort.

11 Nov 1940
On 11 Nov, 1940 northwest of Ireland, in position 56.28N, 14.13W, the British corvette HMS Rhododendron depth charged a German U-boat. This attack was thought to have sunk the U-104 but that turned out to be not the case.

This attack was actually against U-103 inflicting no damage.

21 Nov 1940
During an attack on convoy OB-244 (2 ships sunk) one of the convoy vessels turned to ram the surfaced boat. The boat fired a torpedo towards the oncoming ship but missed and just managed to evade the ramming without any damage. (Sources: Blair, vol 1, page 208)

27 Apr 1943
At 00.05 hours, the outbound boat was attacked by a Leigh Light equipped Wellington aircraft (172 Sqn RAF/M) after being located by radar in the Bay of Biscay. Warned by the radar detector, U-103 evaded the attack and escaped by diving. No damage were caused by the six depth charges that had missed ahead. The aircraft circled the area and homed on a second radar contact, that proved to be U-566 which was unable to dive due to an earlier air attack. The aircraft had no depth charges left and returned to base after exchanging gunfire. (Sources: KTBs/ADM 199-1784)

22 May 1943
At 14.48 hours, the inbound boat was attacked by the British Whitley aircraft Z9440 (10 OTU RAF/N, pilot F/S D.W. Brookes) northwest of Cape Finisterre in the Bay of Biscay. AA fire hit the aircraft (misidentified as Halifax) during the first attack run and prevented the crew from dropping their depth charges. U-103 crash-dived and the only slightly damaged Whitley returned safely to base. (Sources: Franks/Zimmerman)
