WW2 Convoy Routes


Convoys were employed at least from the 16th Century as a form of protection and were used extensively during WW1 and WW2.

There are extensive resources on the web about convoys and this entry is restricted to explaining the prefix codes used for convoys during World War 2 - links to some of them can be found on the War Links page of this site.

Note: This table has been compiled from several internet sources that do not agree 100% so it may contain errors.
