I can't imagine ship fire being this accurate. It is more likely 75 MM from Shermans particularly considering the concentration of hits near the aperture.
Or maybe it was being subjected to engineering tests of German armor. Lots of reverse-engineering was going on to determine how good German armor was and how to defeat it.
Oh yeah. The Navy ships came in close, in the shallow water to provide direct fire support.
They could hit that thing all day long. Besides, the supposedly amphibious tanks went straight to the bottom when they were launched, unfortunately with their crews, all lost.
Tanks didn’t make it to the beach on day one.
I watched the Navy DDs work over Batangan Peninsula in VN in 1971.
They put shells on and around a hootch from a mile offshore.
We felt puny with our mere 50cal.
That does sound plausible. I was just repeating what was written at a private museum on the exit of Omaha Beach. If it was destroyers, that is some shooting!!
