The Siege of Gibraltar stands almost alone in the annals of warfare, alike in its duration and in the immense preparations made, by the united powers of France and Spain, for the capture of the fortress. A greater number of guns were employed than in any operation up to that time; although in number, and still more in calibre, the artillery then used have in, modern times, been thrown into the shade by the sieges of Sebastopol and Paris. Gibraltar differs, however, from these sieges, inasmuch as the defence was a successful one and, indeed, at no period of the investment was the fortress in.
