On 3 January 1943, B-24 Liberator 41-23806 was returning from a raid on St Nazaire. The aircraft had been wrongly led over the coast of Pembrokeshire by the B-17 Flying Fortresses taking part in the mission, and was running low on fuel. Two of the aircraft's engines stalled and the crew attempted a forced landing near Dreenhill, when a third engine stalled causing the aircraft to crash.



One of the crew was killed instantly, while the other injured airmen were taken to the War Memorial Hospital at Haverfordwest. Two of the wounded were transported back to the US, where they died in hospitals shortly after.



A plaque was erected in June 1994 to commemorate the crash.
