Duke of Bavaria, who was himself lying mortally ill nearby, and by Duke Conrad with a large following of Franconian knights. Conrad's unexpected arrival encouraged the warriors so much that they wished to attack the enemy immediately." The arrival of Conrad, the exiled Duke of Lotharingia (Lorraine), and Otto I's son-in-law, was particularly heartening because he had recently thrown in his lot with the Magyars, but now returned to fight under Otto I; in the ensuing battle he lost his life. A legion of Swabians was commanded by Burchard III, Duke of Swabia, who had married Otto I's niece Hedwig. Also among those fighting under Otto I was Boleslaus I, Duke of Bohemia. Otto I himself led the legio regia, stronger than any of the others in both numbers and quality. The main Hungarian army blocked Otto I's way to Augsburg. A contingent of Hungarian horse-archers crossed the river west of Augsburg and immediately attacked the Bohemian legion from the flank. The Bohemians were routed and the two Swabian legions were badly damaged. The Hungarians stopped to plunder the German baggage train and Duke Conrad the Red used the opportunity to attack the vulnerable Hungarians and shatter them. Conrad returned to Otto I with captured Hungarian banners. Conrad's victory prevented the German army from being encircled. Otto I rallied his men with a speech in which he claimed the Germans had better weapons than the Hungarians. Otto I then led the German army into battle with the main Hungarian force, defeating them. How the main Ottonian military defeated the Hungarians, however, is somewhat unclear. This is because Widukind's account of the battle is remarkably short and lacking in detail, which is surprising considering the significance of the battle. This has left some historians to speculate how the battle played out based on the strategies outlined in Vegetius's Epitome of Military Science, which heavily influenced Ottonian strategy. According to these historians, while the infantry approached the center of the Magyar formation, Conrad's cavalry, posted on the left wing and protected on its flank from nearby cliffs, would stay out of range of the Hungarian archers but would also attempt to draw them more to their right. Meanwhile the royal legion, under Otto I's personal leadership, engaged the enemy from the right. Although the King's forces suffered losses from the archers, this gave the royal legion the opportunity to directly assault the
