this victory at the battle of Lincoln put Matilda on the throne. She was never officially crowned and so the first female monarch of England is never usually listed as such.
During the time Ranulf was fighting for the Angevins- Prince Henry gave him the fee of Robert De Caux- Hereditary keeper of the Forest of Sherwood (more on the Keepers of Sherwood Forest soon)- in an abortive grant known as the 'Treaty of Devises' (Crook 1980)
Robert De Caux was a supporter of King Stephen's cause along with William Peverel the younger (son or grandson of William Peverel who had built Nottingham Castle on the orders of William the conqueror in 1087).
William Peverel maintained King Stephens cause against Ranulf in Nottinghamshire.
It seems that Ranulf was attempting during this time to seize control of the keepership of Sherwood Forest and others in Nottinghamshire and Derbyshire by gaining the De Caux barony for himself! (Crook 1980)
Ultimately this failed! But he was very much involved in the destiny of the forest and its inhabitants at the time!
The demise of the Hounour of Peverel and the possession of these lands by the crown would be a seminal moment in the history of Sherwood Forest.
