In the map on Page Two of today’s Times there’s a large gap between Trier (which Patton, after taking it, was told he wasn’t supposed to take it (top-down management, even in war, can be pretty stupid sometimes)), and Cologne, way to the north. The map shows no major Allied operations in this gap. Maybe the Nazi’s missed an opportunity to at least prolong the war?
I may be able to better answer your question tomorrow when I post the German Lage West situation map. There is one for March 3. But as a teaser; there are only about ten maps for the entire month of March, and none at all for April.
It’s all part of the disintegration of the Reich and its armed forces.
