In my personal museum, I have fragmants of artillery round fuses from the Island.
I visited and studied the battlefield there and across the water on Bataan. Our troops both US Army and the Philippines stood with their backs to the wall.
I visited Corregidor too, when I was in the Navy. I sent my father a picture of myself standing at what remained of Battery Cheney, where he served as part of the 60th Coastal Artillery (AA). I’m sure he wasn’t sure that he’d have any offspring at that time, much less one speaking english.
