Today in World War II History—December 19, 1942: 80 Years Ago—Dec. 19, 1942: Free French take Pichon, Tunisia from Germans.

Today saw the high water mark of Operation Winter Storm, the German effort to relieve Stalingrad. German troops advanced to a point 30 miles south of Stalingrad, which is not close in military offensive terms. They could not advance further, and the trapped forces had insufficient fuel to commence an effort to break out.
