The Iron Castle by Angus Donald
AD 1203: ROBIN HOOD MUST TURN THE TIDE OF WAR
AD 1203: England and France are locked in a brutal struggle for power. The fate of the embattled duchy of Normandy is in the hands of the weak and untrustworthy King John. Facing disaster, he calls for help from a former outlaw - Robin Hood.
The Earl of Locksley
As King Philip II's army rips through the Norman defences, Robin - the Earl of Locksley - leads a savage mercenary force into battle under the English banner, supported by his loyal lieutenant Sir Alan Dale. But defeat is only one castle away.
The Iron Castle
The most powerful fortress in Christendom, only Chateau Gaillard can resist the French advance. Robin and Alan must defend this last bastion against overwhelming force - for if the Iron Castle falls, Normandy will fall with it.
