On 16 December 1944, Sherman tanks of Company A, 37th Tank Battalion were the first 4th Armored Division vehicles to enter Germany when they chased several German tanks back into the woods near Rimling. The same day Company A entered the Reich, Hitler had played his last trump north of where the 4th Armored Division was resting from its five months in action. The German 5th Panzer Army, the last of the German strategic reserves, spearheaded the attack by Field Marshal Model's Army Group B that opened the "Battle of the Bulge". Its objective was the port of Antwerp and allied depots nearby.
