The Battle of Veillane (or the Battle of Avigliana) was fought on 10 July 1630 between a French army under the command of Henri II de Montmorency and a Spanish army under the command of Don Carlo Doria.

[2] This was the casus belli but his primary motive was to force Charles Emmanuel I, Duke of Savoy from his alliance the Habsburgs (Philip IV of Spain and Ferdinand II, Holy Roman Emperor) and hence sever the land link between Habsburg lands in Italy and those in Germany and the Spanish Netherlands.

[3] The French commander, General Montmorency, led the royal gendarmes in a charge across a ditch, capturing Doria with his own hand and reportedly fighting like a common soldier until the Spanish withdrawal from the field.

For his achievements during the Piedmont Campaign Montmorency was appointed a Marshal of France later the same year.

[4][5] The outcome of the Piedmont Campaign reversed earlier French strategic losses and the Treaty of Cherasco signed in 1631 was largely favourable to France.
