General Elster surrendered at Beaugency with almost 20000 men (the exact figure is something like 19600).
The difference between this mass surrender and the Falaise pocket is that in Beaugency Elster chose to surrender with ALL his men at the same time. In Falaise there were more prisonners , but it took several weeks to get them , if not more. Now imagine the scene of 20000 soldiers led by officers on horses and fully armed , the germans still carying their colours, saluting and being saluted by American officers. The whole scene has been filmed . It took several days until the last Germans finally crossed the Loire River. I saw a documentary about this story some time ago, I'll try to find the link for you.
