A question was asked on another thread and by Private Message. Starting a new thread seemed a good way of replying and inviting contributions from others.
Stepwilk asks if there are sources which would help in the following:
At which Gosport hards did BARVs embark onto LCTs?
What other vehicles were loaded on the same craft?
What were the movements and activities of the BARVs once ashore?
Some I can answer. Some may need cross referencing and correlation.
I have the landing tables and some parts of the War Diaries. For some reason May, June and August are missing from my copy of 20 Beach Recovery Section War Diary. This may be the most useful.
