APO World War II-hospital

Would a WWII APO address also indicate if a hospital was nearby for a vet wounded in the war? Takeo Kaneichi was with the 442nd RCT, 2nd bn, Company E. Serial #39 084 564. 106th Infantry Division. Wounded Oct 21, 1944 near Bruyeres, France and later died of those wounds Nov 8, 1944. Presume he was initially in a nearby field hospital.

His APO of 758 would indicate the mailing address was in Marseille, France, at that time period but I know of one other 442 vet injured around the same time who said his hospital was in Dijon, France.  If Takeo was injured in northeastern France (Bruyeres), they would have moved him near the APO in Marseille to be in a hospital there?

Lastly, any way to search for those hospital records? Takeo's records were burned up in the 1973 fire.

Appreciate it!
