What happened to the 6th Army after Stalingrad?

The 6th Armee was reconstituted using convalescents, staff troops and a replacement cadre under a man names Hollidt and while it was refitting it was called “Army Group Hollidt”. It was destroyed again during the Battle of Debrecen and was reconstituted a third time and destroyed outside Vienna. The 6th Armee is the only army to be destroyed three times in the course of a single war. After Stalingrad it never had the combat power it did at the time of Stalingrad.
