Attacks on this boat and other events

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

11 Nov 1940
On 11 Nov, 1940, NW 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 U-104, but the target was actually U-103, which escaped unscathed.

21 Nov 1940
During an attack on convoy OB 244 NW of Ireland in which two ships were sunk, one of the convoy vessels turned to ram the surfaced U-103. U-103 fired a torpedo at the vessel, which missed, and just managed to evade ramming. (Sources: Blair, vol 1, page 208)

27 Apr 1943
00.05 hrs, Bay of Biscay, outbound: Wellington bomber M for Mother from 172 Sqn RAF located U-103 on radar and made a Leigh Light attack, but the boat was warned by the radar detector, and dived in time to evade six depth charges which exploded harmlessly ahead of her. The Wellington circled the area and then approached a second radar contact which proved to be U-566, left unable to dive by an earlier air attack. The aircraft had no depth charges left and returned to base after an exchange of gunfire. (Sources: KTBs/ADM 199-1784)

22 May 1943
14.48 hrs, Bay of Biscay NW of Finisterre, inbound: British Whitley bomber Z9440 (RAF OTU 10/N, pilot F/S D.W. Brookes) was prevented from dropping depth charges by heavy and accurate flak on its initial approach. U-103 dived and escaped unscathed. Damage to the Whitley (misidentified as a Halifax) was slight, and it reached base and landed without incident. (Sources: Franks/Zimmerman)

5 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.
