Where Was "A.p.o. 1" In July 1945?

I'm trying to nail down as much as I can about the provenance of the following wartime patriotic cover:



The cover was prepared by Teixeira using a cover with a Crosby cachet. A.P.O. 1 was the Army Post Office for the 1st Infantry, so I suppose it moved around a lot. I have a PDF of a numerical listing of APO's from 1942-1947 but the first page is corrupted. Here is an image:



It is torn off at the top, but I'm pretty sure that the initial listings are A.P.O. 1. What is not entirely clear is whether the dates are when the A.P.O. began at the indicated location, or ended. It seems more logical that it would be the date it began, which would put A.P.O. 1 beginning June 17, 1945, which would put it at Ansbach when this cover was postmarked. Would anybody have any other evidence that would confirm this?

The date and possible purpose of this cover are curious, also. I think it may be in response to Chennault's retirement, but I'm still looking to confirm when that was (though I know it was in 1945).

TIA for any further information anyone might have that would be helpful.

From March 18, 1945 through the duration, A.P.O. 1 was in Germany, according to Forte/Helbock.

That agrees with the listing I presented, with a date of March 18, 1945 for Bonn, Germany. Prior to that it was in Herve, Belgium.

I'm unfamiliar with Forte/Helbock, but it sounds like it might be a useful reference. Do you have a full title?

Is the month marked "IIII"?

EDIT: Oh, that's JUL!

More on the postmark of July 27. Chennault was pressured to resign, and submitted his resignation July 6. It sent shockwaves through his supporters among the Chinese, but the Army leadership wanted him out. His official retirement date was Oct 31, but no doubt Teixeira had learned of his submitted resignation and intended this as an event cover of sorts to honor his service.

Teixeira may have been a Louisiana boy as was Chennault.

Another question. This cover is not censored. Yet it appears to have been mailed to Teixeira's wife, and is neatly opened along the top, as if to remove a letter that was inside. Teixeira covers often have a censor stamp with his own signature. Is it possible that by this date mail from the ETO (European Theatre of Operations) was no longer being censored as the war in Europe was over?

Here's an online guide of Jim Forte's APO numbers:

I'm not sure how to read the data at that site, and it seems incomplete. I gather this is for A.P.O. 1:




How would this tell me where A.P.O. 1 was in July 1945? I think Orstampman must have access to the printed version, and that this web version leaves out the information critical to my question.

Teixeira's Potsdam cover from some days later is marked censored.

By the way, I don't think there is any special significance to the Chennault cover from 27 July. The cachet is not his own and his pre-printed return address is from some time earlier. (Teixeira had already made Captain by this time.) I suspect it's just a letter to his wife.

According to Russ Carter's Numbered Army & Air Force Locations, APO 1 was located at Ansbach, Germany from 17 June 1945 to Jan 1946 when it moved to Kitzingen. Prior to Ansbach, it had been located at Hof.

KGB,

The observation about the date is speculation, of course. But given what you point out about the Potsdam cover, how did it get by without being censored? I admit, the world of WW II censored covers is one I know very little about. That he was a captain by now adds a different twist. Because of that, I would conclude that the cover is one he had prepared with the "corner card" while he was still a 1st Lt. I the timing is curious.

petert4522 cited the reference book above from which the date/location information was gleaned - thanks, Peter! Jim Forte's site has useful info, but doesn't list the date/location info.
