"The Battle of Anzio" would be nice (even though it's Americans vs. Germans), esp. when one company from schwere Panzerjäger-Abteilung 653 was attached to schwere-Panzer-Abteilung 508, which both were assigned to Fallschirm-Panzer Division "Hermann Göring".
The Allied air supremacy and the American naval artillery forced these vehicles to take narrow country roads.. and the heavy rains made these roads even worse. It was a disaster for the Germans, leading to numerous casualties and material losses.
Technical note: Elefants used during this operation didn't carry any tactical numbers either.
