The Great War in England in 1897 by William le Queux

Many British military and naval writers had ridiculed the idea of a surprise invasion without any attempt on the part of the enemy to gain more than a partial and temporary control of the Channel. Although an attack on territory without having previously command of the sea had generally been foredoomed to failure, it had been long ago suggested by certain military officers in the course of lectures at the United Service Institution, that under certain conditions such invasion was possible, and that France might ere long be ruled by some ambitious soldier who might be tempted to try a sudden dash on _le perfide Albion_. They pointed out that at worst it would entail on France the loss of three or four army corps, a loss no greater than she would suffer in one short land campaign. But alas!

at that time very little notice was taken of such criticisms and illustrations, for Britons had always been prone to cast doubts upon the power of other nations to convey troops by sea, to embark them, or to land them. Thus the many suggestions directed towards increasing the mobility and efficiency of the Army were, like other warnings, cast aside, the prevailing opinion in the country being that sudden invasion was an absolute impossibility.
