The 28th Infantry Division (PA Nat’l Guard) was 1 of those units that got steamrolled at the outset of the Battle of the Bulge. They were refitting & getting replacements after the Battle of Huertgen Forest (which was still going on, I believe). They were a battered mix of veterans & green replacements when the hammer fell.
Not so long ago, we laid a hero to rest at Arlington who was in the first battle in Africa, landed at Normandy, and served with Patton on the push to Germany. Also, he had a Silver Star, Bronze Star, and a couple Purple Hearts. And Purple Hearts were harder to get back then. And I would like to add that he was one of the nicest men I ever met. I don’t believe I will ever meet another man like him. He truly was the greatest generation ever.
Not all were inexperienced.
