Collection of medieval European manuscripts documenting the Hundred Years’ War, dating back to 15 March 1347. They document the Battle of Crécy, where English longbowmen defeated French cavalry in Picardy, marking a decisive victory for King Edward III. The manuscripts, originally held at Westminster Abbey, were transferred to the Tower of London in 1356 and acquired by the French National Archives in 1792 following confiscation during the French Revolution. The collection includes works by Geoffrey Chaucer, Jean II of France, and Edward, Prince of Wales (the Black Prince), as well as loans from the Hanseatic League and German merchants to fund the campaign.
