Time to take stock of matters-to bring the situation in hand. The hull was blocking his view. Other than it, all he could see was a sparkling bay, and a stony break-water. He strode into the sea, watched curiously by the man with the mushroom-headed yard, and, once he was out knee-deep, turned around. What he saw then made it more or less obligatory to fall right on his arse.

This bay was spattered with bony islets, close to shore. Rising from one of them was a squat round fortress that (if he was any judge of matters architectural) had been built at grand expense by Spaniards in desperate fear of their lives. And apparently those fears had been well founded because the top of that fort was all fluttery with green banners bearing silver crescent moons. The fort had three tiers of guns on it (more correctly, the fort was three tiers of guns) and every one of ’em looked, and sounded, like a sixty-pounder, meaning that it flung a cannonball the size of a melon for several miles. This fort was mostly shrouded in powder-smoke, with long bolts of flame jabbing out here and there, giving it the appearance of a thunderstorm that had been rammed and tamped into a barrel.

A white stone breakwater connected this fort to the mainland, which, at first glance, impressed him as a sheer stone wall rising forty or feet from this narrow strip of muddy beach, and crowded with a great many more huge cannons, all being fired just as fast as they could be swabbed out and stuffed with powder.

Beyond the wall rose a white city. Being as he was at the base of a rather high wall, he wouldn’t normally expect to be able to see anything on the opposite side thereof, save the odd cathedral-spire poking out above the battlements.
