“The French deemed their position impregnable. Their men-of-war were ranged close together in two lines, and the frigates and guard-boats they considered would be sufficient to divert any fire-ships that might make their way round the boom. Half a gale was blowing on shore. Cochrane himself went in the explosion-ship that led the advance. “The night was dark, and when Cochrane reached what he thought was the vicinity of the advanced ships of the French he lit the fuse, and with the officer and four men with him took to the boat and rowed away. They made but little way against the wind and sea, and the fuse, instead of burning for fifteen minutes as intended, only burned half that time. This, however, was really the means of saving the lives of those on board the boat. She was nearly swamped by the effect of the explosion; but as its force, as intended, took place upwards, the shells and grenades exploded far overhead, scattering their contents over a wide area, and the boat itself lay inside the circle of destruction. We on board the _Impérieuse_, which was anchored three miles away, felt the shock as if the ship had struck heavily on a rock. For a moment the sky seemed a sheet of fire. Then came the crash of the exploding shells and the rattle of the grenades, and then a roar as the fragments and pieces of wreck fell into the sea. “The fire-ships were very badly handled. Many of them were lighted over four miles from the enemy, some were put on the wrong tack before they were left by the crews; and although there were upwards of twenty in number only four reached the enemy’s position, and not one did any damage whatever. Nevertheless, the desired effect was produced—the explosion-vessel was alongside the boom when she blew up and completely shattered it. The enemy were so appalled by the explosion that, believing the fire-ships were equally formidable, they not only made no attempt to divert their course, but with one exception all the French ships cut their cables; and when morning dawned, the whole of their fleet except two ships were helplessly ashore. The tide had ebbed, and they all lay over on their side, with their bottoms exposed to fire, and had Lord Gambier sent but two or three ships in to complete the work of destruction not one of the powerful French squadron would have escaped.
