We continued to besiege the citadel till June, when it surrendered. During the siege I have counted above sixty shells and carcases in the air at once. When this place was taken I went through the citadel, and in the bomb-proofs under it, which were cut in the solid rock; and I thought it a surprising place, both for strength and building: notwithstanding which our shots and shells had made amazing devastation, and ruinous heaps all around it.
