This was the innermost harbor of Manila Bay: a hammock-shaped anchorage slung between two points of land several miles apart, each of which had been built up into a fortress by the Spaniards, or rather by their Tagalian minions, during the century and a half that they had held sway over these islands. The closer of the two forts, just off their starboard, was Cavite: a conventional square, four-bastioned castle thrust out into the water on a slender neck of land, so that the bay served as its moat. A ditch had been dug across that neck so that the landward approach could be controlled by a drawbridge. This ditch was situated at some distance from the castle proper, and the intervening space had been covered with buildings: a crowd of cane houses with more substantial wood-frame dwellings rising out of it from place to place, and three stone churches that had been erected, or were being erected, by various Popish religious orders.
