Battle of Bouvines

Near the village of Bouvines in Flanders, on 27 July 1214, King Philip II Augustus of France beat a larger coalition army under the German emperor Otto IV. Full-scale pitched battles were rare in the High Middle Ages, and this one's effects reached across Europe: it confirmed French control of lands once held by the English kings, cost Otto his throne and so weakened King John of England that his barons forced Magna Carta on him the next year.

Earlier in his reign Philip had conquered large territories from the Angevin kings of England. In 1214 a broad alliance formed to undo those gains. Count Ferrand of Flanders, angry at losing Aire-sur-la-Lys and Saint-Omer to Philip, turned against his overlord, and he was joined by Otto IV, John of England, Count Renaud of Boulogne and the rulers of Brabant, Holland, Lorraine and Limburg. John's plan was to draw the French south towards his own forces in western France while Otto's army advanced on Paris from the north. The northern allies moved slowly, and on 3 July John withdrew to Aquitaine after two clashes with the French.

Philip marched north and chose open ground east of Bouvines and the river Marque, suited to his cavalry. Estimates of the armies vary considerably. The French may have had 6,000 to 7,000 men, including about 1,200 to 1,360 knights and militia from the towns of northern France. The allies may have had just under 9,000, with some 1,300 to 1,500 knights and around 7,500 foot soldiers. Both armies drew up with cavalry on the wings and infantry in the centre, and the only French line of retreat was a bridge across the marshes behind them.

On the French right, the knights of Champagne and Burgundy fought the Flemish horsemen for about three hours in a series of charges. The better-ordered French slowly wore the Flemings down, and when the wounded Count Ferrand was taken prisoner his men gave way.

In the centre, Otto's infantry and knights first drove back the French town militia and reached Philip himself. Foot soldiers pulled the king from his horse with hooked weapons, and he was saved by his armour and by knights who brought him a fresh mount. French counter-attacks then pushed the allies back. In the fight that followed Otto's horse was killed under him; rescued by German lords, he fled the field, and the French seized the imperial eagle standard.

On the allied right, the English commander William Longespée, Earl of Salisbury, was unhorsed and captured. Renaud of Boulogne held out longest, sheltering among a ring of several hundred Brabançon pikemen and riding out from it to attack, until a final French assault broke the ring and he too was taken. Night was falling, and the French did not pursue.

French losses among the knights were light, and infantry losses were not recorded. The allies lost 169 knights killed and many foot soldiers, including several hundred of the Brabançon pikemen. The counts of Flanders and Boulogne and the Earl of Salisbury were captured, together with some twenty-five barons and more than a hundred knights.

Philip returned to Paris in triumph with his prisoners. Otto withdrew to his castle at Harzburg and was soon displaced as emperor by his rival Frederick II. John secured a lenient five-year truce, but his hopes of recovering the lost Angevin lands were finished. Weakened at home, he was forced by his barons to accept Magna Carta in 1215. The victory strengthened the Kingdom of France as a leading power in thirteenth-century Europe, and Philip founded an abbey near Senlis in thanks for it.
