Geoffroy d'Harcourt (died November 1356), called "the Lame", Viscount of Saint-Sauveur, was a 14th century French nobleman and prominent soldier during the early stages of the Hundred Years' War.
In 1339, along with his older brother John IV of Harcourt, he became one of the 50 main Norman barons who pledged to help the King Philip VI of France in a future invasion of England.
[3] Philip VI gave the hand of the heiress to Guillaume, with Geoffroy aggrieved by this rebuttal and began around 1343, a private war against the Tancarville family.
Hoping to regain his Norman strongholds, Harcourt travelled to England where he placed himself in the service of Edward III, whom he paid homage as the King of France.
By letters patent given at Westminster, Edward III promised to procure for him in England some lands, in compensation for those which he had left in Brabant, and to put him in possession of his Norman strongholds.
[5] Edward III made him commander, along with Thomas de Beauchamp, 11th Earl of Warwick, of one of the three army groups which landed at Saint-Vaast La Hougue on 12 July 1346.
