Relief of Thionville

On June 7, 1639, a Spanish and Imperial relief column under Ottavio Piccolomini lifted the siege lines around Thionville and destroyed the besieging French army under the Marquis de Feuquieres.

Aftermath
Feuquières, wounded in the fighting, was captured by the Imperial forces and died in captivity. In recognition of his victory, Piccolomini was created Duke of Amalfi by the Spanish Crown June 28.

In 1643 the Duc d'Enghien capitalised on his victory at Rocroi by pushing on to Thionville, which fell after a stubborn defence by the Spanish garrison.
