Biberac (Wars of the French Revolution).

Fought October, 1796, between the French under Moreau, and the Austrians under the Archduke Charles, who had previously defeated Jourdan at Warzburg, and now turned upon Moreau, who was retreating through the Black Forest. Moreau severely defeated the Austrians, and continued his retreat unmolested.

Bibracte (Gallic War).

Fought B.C. 58, between the Romans under Cæsar and a largely superior force of Helvetii. The battle was a momentous one, for a defeat to Cæsar meant destruction. He therefore sent away all his officers' horses, giving them to understand that they must stand their ground to the last. In the event, the Helvetii were totally routed, and compelled to submit to the domination of Rome.

Bilbao (First Carlist War).

This fortress was besieged by the Carlists November 9, 1836, and was defended by a small Christino garrison. The besiegers took possession of some of the suburbs, which were recaptured by a sortie. Finally, after several unsuccessful attempts, Espartero, at the head of about 18,000 Christinos, drove off the besiegers, December 25, and relieved the city, capturing the Carlist artillery of 25 pieces. In the action the Christinos lost 714 killed and wounded, while the losses of the garrison during the siege amounted to about 1,300.

Bingen (Gallic Revolt).

In the year 70, Petilius Cerialis, who, with four Roman legions, had crossed the Alps from Switzerland, surprised the revolted Gauls under Tutor, in their camp at Bingen. The Gallic legionaries in Tutor's army deserted to the Romans, and Tutor was totally defeated.

Biruan (Tartar Invasion of Kharismia).

Fought 1221, between 80,000 Tartars under Katuku, and the troops of Jellalladin, Sultan of Kharismia, 60,000 strong. The Tartars were routed and driven from the field in confusion.
