Anchor that made it possible

Before the artificial harbor could work as a way to bring in supply ships--and therefore supply the troops fighting the Germans inland in Normandy--a problem had to be solved: How could you anchor the Phoenixes to each other in such a way that they would not sink, split apart, or otherwise be made useless by heavy waves or bad weather?

The problem was first raised by Winston Churchill in 1942. But the solution came from British Maj. Allan Beckett, who, according to a plaque in Arromanches, designed "the floating roadways, their piers, and the 'Kite' anchors, which enabled the harbor to survive the storm of June 13 to 18, 1944, and to become the key to victory in Normandy.

This is one of the 'Kite' anchors designed by Beckett.
