<P> On 15 June, revolt broke out in Cambridgeshire, led by elements of Wrawe's Suffolk rebellion and some local men, such as John Greyston, who had been involved in the events in London and had returned to his home county to spread the revolt, and Geoffrey Cobbe and John Hanchach, members of the local gentry . The University of Cambridge, staffed by priests and enjoying special royal privileges, was widely hated by the other inhabitants of the town .

The people of the town then opened the gates to let the rebels in . They began looting buildings and killed Reginald Eccles, a local official .

The mayor and the town mobilised their defences, including a local militia, but the rebels never arrived . John of Gaunt was in Berwick when word reached him on 17 June of the revolt . Not knowing that Wat Tyler had by now been killed, John of Gaunt placed his castles in Yorkshire and Wales on alert .
