But Utah had neither bluff nor houses. There were some fixed defenses, made of reinforced concrete, containing artillery and machine-guns. The biggest was at La Madeleine, in the middle of Utah (the fortification took its name from a nearby religious shrine that dated back to Viking days). But the gradual slope and low sand dunes at Utah meant that getting across and beyond the beach was not going to be as difficult as at Omaha. The problem at Utah was what lay inland. Behind the sand dunes was low ground, used by the Norman farmers for grazing cattle. Four narrow, unimproved roads ran inland from the beach; these roads were raised a meter or so above the ground. Field Marshal Erwin Rommel, the German commander, had flooded the fields, with the idea of forcing any troops and armor coming inland to use the roads ("causeways," Eisenhower's planners called them). Rommel had most of his artillery in camouflaged positions or reinforced casements and bunkers back from the flooded area, where it could bombard the roads; Rommel had his infantry prepared to take up defensive positions along the western end of the roads, where it could repel any troops moving up them ...
