Projection of the fire range of the fortifications at the Porto Marie and Santa Cruz Bay

Title Leupe: Profilen voor de Bayen van Porto Marie en St. Cruz.

This sketch belongs to a series of plans (VEL1462-VEL1472) to fortify the Piscadera, Saint Michiel and Porto Marie Bays with a small battery and a fort. This drawing shows the range of the cannons located at the small battery as well as the fort. The dotted diagonals indicate this range. Note the sea level differs for both bays and two horizontal lines are drawn for them.
