Two of the _Tigre's_ 68-pounders, mounted on native craft lying in the little port near the water-gate, opened upon them with shells, while two guns, manned by British sailors, one on the castle of the lighthouse, the other on one of the ravelins, poured grape into them. But the column moved on. The tremendous cannonade from their batteries overpowered that from the guns on the walls, and they suffered but little from the fire from the ravelins, as they had, the night before, constructed two breastworks from the end of their trenches to the breach, the materials used being sandbags and the bodies of their own slain.
