Turn 11. Still no pre-planned artillery falling on my head. Still no activity at all on my right flank.
Your two-turn estimate may be accurate - the whole U.S. line near the center of the map suddenly pulls back into the woods under heavy MG fire. Clearly they have been taking too many casualties and achieving too little.
But near the western edge of the map, my opponent continues to increase pressure and I feel that the engagement is moving to its critical stage here. While my mortar pummels the enemy medium mortar position in the rear, a 60mm mortar round lands close to my AT gun - not too close to cause any trouble but close enough for me to notice. Did he aim for the gun - does he know? Or did he aim for the MG nearby? The 3rd AFV contact turns out to be another M10: my opponent wanted to be prepared for a Panther but now, as I don't have tanks, he prefers to feed the less valuable tank destroyers to my AT guns. An M10 carries 13 HE rounds, a 76mm Sherman carries 39. The M10 parks outside the hedgerow barrier and outside the FOV of the AT gun.
I think I heard the sound of a U.S. HMG - probably M1917A1 - but don't see where it fired from or what it fired at.
Three of my own HMG's are reloading, for the first time since the start of the battle. This includes both HMGs guarding the critical westernmost approach. That's 30 seconds out of action.
The crew of the disabled AT gun, which is in direct contact with the Americans, gets under fire and runs around in panic - one man gets hit, but the leader also joins in with his MP40 and takes out an enemy solider, for a total of 5 confirmed U.S. casualties this turn. Also, it is them who identify the AFV as an M10 - no one else has LOS. The kill tally is 21:10 now, but the actual U.S. losses are certainly higher than 21.
What's next? I make a difficult decision and order the AT gun to hide, hoping it will survive a light mortar attack this way. If the M10 moves forward in the next turn, hopefully it won't do much damage. At the same time I target the presumed light mortar position with my own mortar - which has been far too busy since the start of the battle but I hope I can relieve it soon with fresh reinforcements.
