Hard by Sandgate Castle stands the centenary monument on the modest parade to Sir John Moore, the hero of Coruña, unveiled November 19th, 1909. The spot is appropriate because, at the back of Sandgate, up away out of sight, is Shorncliffe Camp, closely associated with that distinguished soldier. The military works in these parts, along a coast so peculiarly exposed to foreign invasion, are many and important. Henry the Eighth, as we have seen, was diligent in fortifying these low-lying shores, and there came a time, two hundred and sixty-five years later, when the Government of that day was equally concerned about a possible French attack. Then, in 1805, was constructed the famous “Royal Military Canal,” which extends a distance of about twenty miles from Rye to Hythe, with its sluices here at Seabrook, adjoining Sandgate railway-station. The canal is thirty feet wide and nine feet deep in the middle. Its function was, in connection with a regular line of martello towers on the beach, to hamper and impede a landing-force. “Mr. Pitt’s Military Canal,” as it was in those days styled, formed the target for many shafts of ridicule. “The French,” said Ingoldsby, “managed indeed to scramble over the Rhine and the Rhone, and other insignificant currents, but they never did, or could, pass Mr. Pitt’s ‘Military Canal.’” Here, where the Canal’s sluices pour their waters into the sea, are remains of military works, intended to defend this vital spot, with Shorncliffe Camp above. The world wags still with an amiable slowness here, the old horse-tramway through Sandgate to Hythe, belonging to the South-Eastern Railway, leaving the main road and progressing along the beach. The only trouble is the constant succession of motor-cars, generally racing at illegal speeds along these flat roads and producing clouds of dust. [Illustration: HYTHE.]
