Prince of Wales coming on board and so hand called half an hour earlier. Cleaned into No. 3’s. Prince of Wales came on board at 9.30 but saw nothing of him. Put to sea at 11.30. Head down in afternoon. Had First Watch. Thuoght there was something doing about 9 o’clock as light cruiser switched on Searchlight and we passed some object to Starboard. Do not know what it was but may have been burning derelict.
