Anti-tank

""For the first time in 125 years a powerful enemy was now established across the narrow waters of the English Channel. ... Many people must have been bewildered by the innumerable activities all around them. They could understand the necessity for wiring and mining the beaches, the anti-tank obstacles at the defiles, the concrete pillboxes at the cross-roads, the intrusions into their houses to fill an attic with sandbags, on to their golf-courses or most fertile fields and gardens to burrow out some wide anti-tank ditch." So wrote Winston Churchill in Their Finest Hour, published in 1949."
