The Battle of the Herrings was a military action near the town of Rouvray in France, just north of Orléans, which took place on 12 February 1429 during the siege of Orléans. The immediate cause of the battle was an attempt by French forces, led by Charles of Bourbon, Count of Clermont, to intercept and divert a supply convoy headed for English forces. The English had been laying siege to the town of Orléans since the previous October. The French were assisted by a Scottish force led by the Constable of the Scottish army, Sir John Stewart of Darnley.
