This is one of a few photos in the museum by Robert Capa (1913-1954) who recorded the liberation of numerous cities. This is a US soldier who is herding German soldiers following the Battle of Leipzig in April 1945. As a series of photos, they’re thought provoking and interesting.
The city was in ruins with over half the buildings destroyed and the infrastructure shattered from air raids. The German soldiers still alive might have been afraid of the US soldiers depending on what stories they had been told, but there must have been so much relief that this war seemed to be coming to an end.
There’s another photo in this series, which was likely taken by Capa shortly afterwards.
