Convoy Rule in Axis & Allies 1940: Calculating Damage

The Convoy rule in Axis & Allies 1940 (Europe, Pacific, Global) isn’t the most easily written rule in the rule book. Below is a summarized version.

If an enemy warship is in an opponents’ sea zone with a ‘convoy’ marker, the IPCs collected at the end of a turn can be reduced based on convoy damage inflicted, per below.

How many dice do I roll?

  • for each battleship, cruiser, destroyer: roll 1 dice
  • for each submarine or air unit (air unit on a carrier): roll 2 dice

How do I calculate IPC damage?

  • Ignore rolls of 4 or higher
  • Add up the values of the remaining dice (i.e. rolls of 3 or less) to determine the total IPC damage*

* the total damage value cannot exceed the IPC value shown on the board for the adjacent defending territory/territories — even if it’s on the receiving end of multiple convoy disruptions.

An example of convoy damage calculation, as swiped from the rule book:

    Can you chose to not do convoy disruption? For example Germany is about to take London on the next turn. Why deplete London’s cash if you are about to take it?

      My understanding is that it’s optional — You can choose not to. Half the time we forget to?! Heh. Thanks for the comment.
