Historical novel. The Preface begins: "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 any danger of capture, save by hunger. At that period England was not, as she afterwards became, invincible by sea; and as we were engaged at the same time in war with France, Spain, Holland, and the United States, it was only occasionally that a fleet could be spared to bring succour and provisions to the beleaguered garrison. Scurvy was the direst enemy of the defenders. " According to Wikipedia: "George Alfred Henty (8 December 1832 - 16 November 1902), referred to as G. A.
