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 damages. (Sources: Blair, vol 1, page 208)
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)
4 recorded attacks on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-103 did not suffer any casualties (we know of) until the time of her loss.
