Battle of Saint-Quentin

Type of action: Ground battle in the Valois-Habsburg War

Date: August 10, 1557

Location: Along the Somme River (south of Saint-Quentin in Picardy, France)

Combatants: 47,000 Spanish (Habsburgs) vs. 24,000 French (Valois)

Principal commanders:Spanish, Duke Emmanuel Philibert of Savoy (1528–1580); French, Duke Anne Montmorency (1528–1580)

Result: French failed to relieve Saint-Quentin

On August 1, 1557, Duke Emmanuel Philibert of Savoy’s forces laid siege to Saint-Quentin. Henry II of France ordered Duke Anne Montmorency to take all available men to relieve the city. Able to collect only about 24,000 troops, Montmorency intended to avoid battle but put reinforcements into Saint-Quentin. Early on August 10, Montmorency approached the marshes south of the city to slip men into the besieged place. Unexpected problems delayed them, and few made it into the city before the French found themselves facing the assembled enemy forces. Montmorency’s reluctance to retreat before his mission was accomplished prevented the French from effecting an orderly withdrawal. Also his failure to guard a ford across the Somme allowed Savoy to use his cavalry to catch the French before they had gotten far. The French lost more than 2,500 men killed, and some 6,000 were captured, including Montmorency.

Although the road to Paris lay open, Philip II of Spain decided not to risk pushing forward while Saint-Quentin remained untaken. He ordered his army back to the siege lines, and the place fell on August 27. Philip then concluded it was too late in the season to march on Paris and put his army into winter quarters.

Significance

After the French defeat, Henry II assembled a large army to protect Paris. When Philip failed to advance, he sent it against Calais early the next year.
