The Wikipedia article of the day for September 12, 2019 is Chevauchée.
Lancaster's chevauchée of 1346 was a large-scale mounted raid directed by Henry, Earl of Lancaster, in south western France during the Hundred Years' War. The main English army had defeated the larger French army at the Battle of Crécy in August, and French defences in the south west were left weak and disorganised. Lancaster took advantage by leading a raid between 12 September and 31 October 1346 while sending other forces into Quercy and the Bazadais. All three offensives were successful, with Lancaster's chevauchée, of approximately 2,000 English and Gascon soldiers, meeting no effective resistance from the French, penetrating 160 miles (260 kilometres) north and storming the rich city of Poitiers. His force then razed and looted large areas of Saintonge, Aunis and Poitou, capturing numerous towns, castles and smaller fortified places as they went. The offensives completely disrupted the French defences and shifted the focus of the fighting.
