This has been a long time coming. To square (pentagon) it up, I printed a pentagon to the outside dimensions of the walls.

It is to be my Ft McHenry, though I believe it to be somewhat larger in scale. I threw a Hebe frigate in the background for comparison.

Just out of curiosity, does anyone know for sure if Fort M had grass on the walls in 1814? I thought that was a Civil War thing to deal with exploding shells.
