TIL Soviet composer Blanter was made to hide in a closet during negotiations with Nazi Germany because a military commander objected to his civilian clothes. He fell out as the Germans were leaving.
Blanter accompanied the Red Army to Berlin in early 1945. He was commissioned by Stalin to compose a symphony about the capture of Berlin. However, when Vasily Chuikov was meeting with a German delegation led by Hans Krebs to negotiate their surrender following Hitler's suicide, Chuikov had several uniformed war correspondents pretend to be members of his general staff in order to appear more professional and intimidating at the negotiations. But Blanter was also meeting with Chuikov at the time the delegation arrived and he could not pass as a Red Army officer as he was wearing civilian clothes. Thus, Chuikov shoved him into a closet just before the delegate entered the room. While he remained there for most of the conference, he eventually lapsed into unconsciousness from a lack of air, collapsing out of the closet and into the room just as the delegates were preparing to leave, embarrassing Chuikov and astonishing the Germans.
Maybe lack of judgement by Chuikov.
Many would be way more wary of the civilian in a standard suit accompanying all that brass than of the nth soldier in normal uniform.
