A view of the gun, recently repainted by Jerry Doherty and H. Buck Urban. The gun's shield shows damage from the battle.
The gun is apparently the second gun on the port side of the ship -
the side of the ship facing the American ships. The charts
of
hits prepared by the U.S. Navy indicates this gun took a hit to
the shield at this location. The steel in the shield is approximately
one inch thick. The report on the effects of U.S. gunfire on the INFANTA MARIA TERESA
states of this gun:
"An 8-inch sheel struck the shield of the second 5.5 inch (14 centimeter) gun, passed through it, ranging aft, and exploded. The effect of the explosion upon almost everything about the decks in that vicinity must have been terrific."
