The book says to defend against a salient, first secure the shoulders and stop it from widening. Holding St. Vith for so long and then holding at Elsenborn Ridge and Bastogne accomplishes that here. The Germans are canalized into a narrow area that really isn’t capable of sustaining an advance to Antwerp.
Thanks for explaining that. I don't know "the book," so it's been helpful to read such posts by you, Homer, henkster, alfa6, etc.
I just finished reading about Elsenborn, obviously will focus on Bastogne, but now realize that St. Vith demands attention.
Holding the “Fortified Goose Egg” at St. Vith will be one of the finest stands of the United States Army.
