English forces under Sir John Fastolf defend a supply convoy carrying rations to the army besieging Orléans in the Battle of the Herrings.

The Battle of the Herrings, also called the Battle of Rouvray, was a military action near the town of Rouvray in France, just north of Orlans, which took place on 12 February 1429, during the siege of Orlans in the Hundred Years' War. The immediate cause of the battle was an attempt by French and Scottish forces, led by Charles of Bourbon and Sir John Stewart of Darnley, to intercept a supply convoy headed for the English army at Orlans. The English had been laying siege to the city since the previous October. This supply convoy was escorted by an English force under Sir John Fastolf and had been outfitted in Paris, from whence it had departed some time earlier. The battle was decisively won by the English.

According to Rgine Pernoud, the supply train consisted of "some 300 carts and wagons, carrying crossbow shafts, cannons and cannonballs but also barrels of herring". The latter were being sent since the meatless Lenten days were approaching. It was the presence of this stock of fish which would give the somewhat unusual name to the battle.

Sir John Fastolf (6 November 1380 – 5 November 1459) was a late medieval English landowner and knight who fought in the Hundred Years' War. He has enjoyed a more lasting reputation as the prototype, in some part, of Shakespeare's character Sir John Falstaff. Many historians argue, however, that he deserves to be famous in his own right, not only as a soldier, but as a patron of literature, a writer on strategy and perhaps as an early industrialist.
