The army of the Holy Roman Emperor defeated the French army in Italy, but funds were not available to pay the soldiers. The 34,000 Imperial troops mutinied and forced their commander, Charles III, Duke of Bourbon, to lead them towards Rome. The Sack of Rome in 1527 was executed by some 6,000 Spaniards under the Duke, 14,000 Landsknechte under Georg von Frundsberg, some Italian infantry and some cavalry.
