Protestant princes of the Schmalkaldic League concluded the Treaty of Chambord with Henry II of France, transferring the Three Bishoprics—Toul, Verdun, and Metz—to French control. Charles V refused to accept this loss and mobilized Imperial forces to retake Metz from its French garrison, seeking to reverse French gains in the ongoing Italian War of 1551–59.
Charles V besieged Metz from 19 October 1552 to 2 January 1553, directing heavy cannonades that destroyed large portions of the city's medieval fortifications. Despite the bombardment, the French garrison commanded by Francis, Duke of Guise held firm. Disease—typhus, dysentery, and scurvy—ravaged the Imperial army, forcing Charles to abandon the siege and withdraw, leaving behind his sick and wounded.
The failed siege left Metz under French protection as a quasi-independent republic (République messine). Habsburg military prestige suffered a notable blow, and French control of the Three Bishoprics was effectively consolidated. The arrangement was not formally codified until the Treaty of Westphalia in 1648, which officially recognized French annexation of Metz.
