Cornhill was constable of Rochester Castle in 1215 on behalf of its then holder Stephen Langton, archbishop of Canterbury. He opened its gates to William d'Aubigny and his troops, whom the barons rebelling against King John had sent to the castle to hold it against the King. He held out against the King's two-month siege. In 1216 he was appointed Keeper of the King's Ports and Galleys.

Through his wife Maud Cornhill had a claim to the stewardship of St Augustine's Abbey, Canterbury, which he and his wife quitclaimed for 80 marks and in land by fine in 1197. In 1203 the prior and convent of Prittlewell Priory, in return for a quitclaim of a moiety of the advowson of the church of North Shoebury, granted to Reginald and his heirs the perpetual right to present one clerk to be a monk in their house.
