1 Jan 1942
The boat was attacked by an enemy aircraft. No damage.

6 Oct 1942
The boat fought an epic battle with the British corvette HMS Crocus off the coast of Sierra Leone, west Africa on 6 Oct. 1942. The U-boat lost three men (including the IWO) and several men were wounded, including the commander, Peter Erich Cremer. The boat was heavily damaged and limped back to base with the help of a replacement WO, Kptlt. Lorenz Kasch, from U-107. The doctor from the milch cow boat U-459 tended the wounded. Cremer then spent three months in hospital. [Oberleutnant zur See Bernhard Hermann, Bootsmaat Heinz Kurze, Maschinenobergefreiter Erwin Levermann].

21 Oct 1942
The former U-570 (captured 27 Aug. 1941) on her first patrol in British service as HMS Graph, commanded by Lt Cdr Peter Marriot, fired a spread of torpedoes at the heavily damaged inbound U-333 north of Cape Ferrol, Spain. Alert lookouts spotted the tracks and U-333 took successful evasive action. It only became apparent after the war that this attack was by the former U-boat. (Sources: Blair, vol 2, page 69)

4 Mar 1943
Aircraft attack, aircraft shot down:British Wellington Mk.VIII MP505 (RAF Sqdn 172/B, pilot F/O G.D. Lundon)

21.31 hrs, Bay of Biscay, outbound: the Wellington caught the lookouts unawares, but when the aircraft switched on the Leigh Light, it was brought down by flak and crashed in flames after passing over the boat, killing the six aircrew. Two of the four depth charges dropped actually hit U-333, but one broke up without detonating and the other bounced off, causing only light damage.The same aircraft and crew had sunk U-268 on 19 Feb.

4 Nov 1943
While hunting a KMS convoy bound for Gibraltar, U-333 surfaced in heavy fog and soon found the convoy, but was driven under by a destroyer and heavily depth charged. Once again, she escaped. (Sources: Blair, vol 2, page 447)

18 Nov 1943
U-333 collided with an Allied escort for the third time in her career when attacking the combined convoys MKS 30 and SL 139. The British frigate HMS Exe rammed the boat, breaking off the periscope, and then with other escorts (and an aircraft) depth charged the boat for eight hours, but once again U-333 escaped. (Sources: Blair, vol 2, page 459)

21 Mar 1944
The boat was sighted west of Tiree in the Hebrides by Allied aircraft which in brought in the famous Support Group 2 (Cpt. Walker), which then hunted the boat aggressively. KL Cremer bottomed the boat at a depth of 40m (131 ft) for ten hours and despite considerable problems "unsticking" from the muddy seabed, U-333 managed to surface and again escaped. (Sources: Blair, vol 2, page 496)

10 Jun 1944
An Australian Sunderland flying boat (Sqdn 10, pilot H. A. McGregor) attacked the boat causing severe damage, but accurate flak repelled the aircraft. The boat was attacked again the next day. (Sources: Blair, vol 2, page 583)

11 Jun 1944
Aircraft attack, aircraft shot down:British Sunderland flying boat (RAF Sqdn 228/U, pilot M. E. Slaughter)

Severe damage to U-boat. U-333 had already been hit by Australian Sunderland Y/10 the day before. Further damage from this attack forced her to return to La Pallice, France.

12 Jun 1944
Aircraft attack, aircraft shot down:British Sunderland flying boat S for Sugar, RAF Sqdn 201

Bay of Biscay south of Brest. This is a possible match. Either this Sunderland or U Uncle from 228 Sqdn were shot down by U-333 on this day. (According to the book Wavetops at My Wingtips, it was 201/S, its demise being witnessed by the crew of a Canadian Catalina flying boat).

10 recorded attacks on this boat.
