John Gaspar Ferdinand de Marchin, Comte de Granville

At the age of thirteen Marchin was enlisted in the regiment of the Count of Tilly and fought many battles in the Thirty Years War.

When the peace was signed on 30 July 1653, Marchin, like Condé, refused the amnesty and went to Spain where Philip IV appointed him company commander in his army.

He participated in the disastrous campaign in the Portuguese Restoration War under John of Austria (1663–1664).

He also led the Spanish troops against the French in the north of France, where he was defeated in 1667 by François de Créquy.

Marchin then retired to his estate at Modave Castle, where he spent his entire fortune on its restoration, which took 15 years.
