Dyle (Norman Invasion of France).
Fought 896, between the Norman invaders, and the Germans under Arnulph, Emperor of Germany. The Normans were totally routed with enormous loss.
Dyrrachium (Civil War of Cæsar and Pompey[Cæsar and Pompey]).
Fought B.C. 48, between the Cæsarians, under Julius Cæsar, and the Pompeians, under Pompey. The latter having formed an entrenched camp some distance from Dyrrachium, Cæsar interposed his army between the camp and the town. This interrupted Pompey's communications, and he, in consequence, attacked the Cæsarian lines, which he forced, at the cost of 1,000 men, and obliged Cæsar to retire.
