But the most brilliant object in Jack’s vision was neither the Bridge nor the City. On the northern bank of the river, downstream of the Bridge, rose the Tower. Jack recalled this as a dull stone pile with the occasional candle gleaming through an embrasure. But on this night, anyway, the Tower was a massive stone plinth supporting a pillar of airborne light, and all the ships in the Pool below it seemed to have collected around its radiance like gnats besieging a lanthorn. Actually the eastern end of the place was as dark as ever, but at its western edge hot fires had been kindled. Piles of smoke and steam were rising up to black out the stars, and sparks careered through those clouds like meteors. The flames were concealed behind Tower walls, but they lit up their own smoke from beneath, and made of it a screen to project boiling and flaring light across the water. "Closer, closer," Jack kept demanding—it had become obvious that the captain was under orders to do Jack’s bidding no matter what. So sailors were sent below to work the sweeps, and, like a many-legged insect crawling through a crowded burrow, the brig felt its way among anchored ships for hours, shrugging off curses and threats from men on other vessels who did not want to see their anchor cables fouled.
