The wild cheer of our lads as they broke cover and rushed across the narrow open space which still separated them from the battery was evidently the first intimation to the garrison that anything was wrong, for our sudden appearance seemed to take them absolutely by surprise, with the result that something very like a panic ensued among them.  A few, after staring at us agape and motionless for a second or two, as though unable to comprehend what we were after, came to life and took to their heels, attempting to bolt out of the battery before we could reach it.  But our lads quickly stopped them by spreading out in front of them and driving them back at the point of the cutlass; others, seeing the impossibility of retreat in that direction, dashed into one of the chambers beneath the gun platform, slamming the door behind them, regardless of the fact that they were shutting out many of their comrades, and barricading themselves against attack, as we could hear by the sounds proceeding from the inside; while, as for the two sentries on the platform, they simply fired their muskets in the air, flung them down, and vaulted over the parapet on to the glacis, thus making good their escape.  The six men charged with the duty of spiking the guns dashed straightway up the steps leading to the gun platform, and at once proceeded to the execution of their task, leaving their comrades below to deal with the garrison; and in less than five minutes the battery was in our possession, and the six guns effectually spiked.  True, a few of the artillerymen who had retreated to the interior of the structure thrust muskets through the windows of the chamber and snapped them off at us; but they speedily gave that up and surrendered at discretion upon my approaching a broken window and shouting through it, by Mr Adair's orders, the information that we were about to explode the magazine, and that they had better come out if they did not wish to perish amid the ruins.
