I know that Naval units do not have to stop if there is an enemy sub or transport present. I know a sub can by pass naval units if there is no destroyer present. I may have already answered my question without realizing it but please help anyways.
Can your attacking naval force bypass an enemy sub even if you have a destroyer in that naval force?
Do subs stop subs?
Here is the situation Germany has a naval force with destroyers in SZ112 they want to move to and invade from SZ127. Russia has on sub in SZ 125. Can the whole German naval force bypass the sub? If not can Germany first move the naval force without destroyers to Z127 and then move the destroyers to SZ125 and kill the Russian sub?
