I have just been made aware of a particularly valuable resource which will come as a godsend for those researching WWII ships and/or convoys.

If you visit Convoy Web you will find an option to "Multi-Convoy Web Search" - using this you can search over 1,160 convoy pages across the Web (including pages from this site) for a particular vessel.

Definitely recommended - and it works brilliantly!  Do try it.
