In 1942, somebody at the War Office had another look into the tunnel situation, this time for the purpose of finding out if it would be practical for the British to start tunneling under the Channel—the idea presumably being the creation of a supply route to France ahead of an Allied invasion, with the last leg of the route being completed once the Allied Armies had installed themselves on the French coast. Again, several prominent British civil engineers were called into consultation, but the subject was abruptly dropped, without investigation of the problem of disposing of the spoil, when the engineers estimated that a tunnel probably would take eight years to complete—three years longer than the war then was expected to last. From 1940 on, the British kept a routine watch on their reconnaissance photographs for signs of tunneling on the French side, especially around the site of the still existing shaft of the French Tunnel Company at Sangatte. Early in 1944, R.A.F. and U.S.A.F. reconnaissance showed signs of unusual installations being made near Sangatte, but these later turned out to be unconnected with subterranean workings. As it happened, they were launching sites for V-2 bombs. The actual handling by the Germans of the old tunnel shaft during the occupation of France was rather peculiar. Far from trying to continue the existing tunnel in the early part of the Occupation, they treated it in contemptuous fashion, using the shaft as a dump for old chunks of machinery, used shell casings, bits of rubbish, and broken slabs of concrete. Later on, their attitude changed drastically. They sealed the top of the shaft with a poured-concrete platform. Then, in weirdly romantic fashion, they built a large rim of fitted stone around the platform to create an ornamental-wall effect, and added around the well a grass-and-flagstone terrace complete with formal walks and sets of monumental-looking stone steps laid out in symmetrical style. Apparently their notion was to bring the tunnel aesthetically into harmony with a military cemetery they installed between the tunnel entrance and the sea.
