I was coordinating the whole show. The crucial decision, for which I was already tensing though» I had a few minutes yet, was when to lift the straight-line, overhead fire of the tanks and TDs. Artillery was also laying down an intense barrage on the hilltop, but its shells arced in with plenty of clearance of the ground troops and could be lifted later. The tough decision was when to lift the 75s and 90s. If I stopped the firing too soon, the Germans would rush out of their bunkers and blast our men when they were exposed on the open slope. If I waited too long, I might wipe out my men from the rear.
