@Private-Panic said in Attacking multiple territories in one combat move?:

Also subs not involved in combat can move into hostile sea zones in which there is no enemy destroyer present.

A small correction: Subs can even move into seazones containing an enemy destroyer:
Rulebook, 1941, page 20:

Submarines: Unlike other sea units, submarines can move through and even into hostile sea zones during this phase.
However, a submarine must end its movement when it enters a sea zone containing one or more enemy destroyers.
