England

• John of England captures a party of 18 French knights and many men-at-arms, in the ongoing conflict against France.^[1] His brother, King Richard I (the Lionheart) introduces a new Great Seal – in an attempt to keep the war against France funded. The government proclaims that charters previously struck with the old seal are no longer valid and must be renewed with a fresh payment.^[2] The office of Lord Warden of the Stannaries is also introduced, to tax the produce of tin mines in Cornwall and Devon.^[3]
• September 27 – Battle of Gisors: Richard I defeats the French forces led by Philip II (Augustus) at Courcelles-lès-Gisors, in Picardy. Richard captures three castles on the border of the Vexin. The French troops, many of them mounted, crowd the bridge leading into Gisors Castle but it collapses beneath them. The French king is among those who plunge into the water in his armor. Many French knights drown, but Philip is pulled to safety.

Levant
