Convoy routes
More than 200 convoy-routes existed in the war, here we show most of the routes which U-boats attacked, from here you can go to every convoy-route to see all the attacked convoys and some details.
Each convoy was known by two or more letters, usual meaning the the departure and destination harbours, i.e. the AB convoys sailed from Aden to Bombay and BA convoys returned from Bombay to Aden. But also were used the H for Home and the O for Outward, i.e. HX meant for \'Home from Halifax\'. The lettering was also used to indicate the convoy's speed. The HX-convoys were allways fast ones and the SC's were slow ones.
The convoys received a number when they left the harbour, like BA-2 or HX-348, some convoys ended up with a number over 100 like the HX, SC, ON and OB convoys.
