18 Sep 1944
At 21.07 hours, the boat was attacked by a B-24 Liberator (224 Sqdn RAF/H) west of Stadlandet, Norway. The AA fire was temporarily silenced by the front gunner, but the six depth charges fell on the starboard side, apparently causing only minor damage. U-867 kept firing at the circling aircraft and then escaped by diving, leaving a small patch of oil behind. Both diesel engines had been disabled in heavy weather the day before and the boat was making for the coast when attacked. (Sources: BdU KTB/ADM199-1786)

19 Sep 1944
The sinking of U-867: On 17 September, both diesel engines had been disabled in heavy weather and the boat had headed towards the coast until the batteries were almost empty, waiting for U-218, U-858 and U-1228 which were ordered there to give assistance by BdU (C-i-C U-boats). On 18 September U-867 and U-1228 were attacked by Liberators and the latter was left damaged and forced to return to base. At 17.37 hrs on 19 September U-867 was found and attacked by another Liberator (224 Sqdn RAF/Q, pilot FL H.J. Rayner), but the six depth charges dropped overshot. However, the pilot reported that the U-boat was already losing oil before the attack and that dinghies were visible alongside. Apparently this attack had so demoralised the crew that U-867 was scuttled while the aircraft circled the area, counting some 50 men in rubber dinghies. U-218 and U-858 both heard the detonations from close by and headed towards the area, but the latter was attacked by another Liberator at 20.10 hrs. The large oil patch and 21 dinghies sighted by the crew of that aircraft following its attack on U-858 were actually from U-867. Despite being so close, neither U-boat was able to locate the survivors due to bad weather, and the search for them was abandoned on 22 September. (Sources: BdU KTB/ADM199-1786)
