I was thinking the same
I've been reading the movements of the 5ht Infantry Division, described in the "Escape from Kalisz" adventure for the campaign we're running. These movements seems to me somewhat strange, if the objective of the offensive was the Baltic Coast. The advance of the 5th ID from the departure position follows the South / South-East direction during more than 150Km! Too far away as for cover the southern flank of the advance, if it is what the genius planner had intended for the 5th. Anyway, the commander of the 5th lead his unit to a good mousetrap showing great gallantry.
For sure the response to "Good luck, you're on your own" could be "Don't worry, better alone than in bad company".
