Was III Corps supposed to stay behind during Omega?

[Olefin]

An interesting question and not sure if its been debated here before - did anyone notice this in Going Home? Its on page 24 of the module

BETWEEN FRANKFURT-AM-MAIN AND WURZBURG

At the beginning of the adventure, the 2/2nd US Armored Division,
and elements of the 44th US Armored Division are moving
towards Bremerhaven to participate in the evacuation, even
though the order did not apply to them.

Does this mean that the Omega evacuation originally wasnt supposed to include the US III Corps?

If you look of the four units making it up 1st US Cavalry Division decided to stay in Germany as did the 3rd ACR and the HQ (with the exception of 600 men and 5 AFV's) but then it implies they disobeyed orders to do so.

However you then have the above entry on page 24.

If the III Corps was orginally meant to stay behind it does change the idea of Omega somewhat - i.e. from an abandon ship type evacuation where MilGov basically pulls out of Europe to possibly more of a strategic withdrawal of most forces but leaving at least one army behind (i.e. the III Corps and the XI Corps combined) to still have a say in the fighting and eventual outcome of the war

If so then did the pull out of the 2nd of the 2nd and the 44th against orders turn it into an "everyone to the boats" scenario and ruined that plan?

Or does it mean that the US 1st Cav Division and the III corps HQ were actually following orders when they didnt evacuate and thus are still under MilGov orders participating in what's left of the fighting there?

Has this been discussed before and I cant find it among the threads?
