Early in March 1554 the three English reformers and later Oxford martyrs, the archbishop of Canterbury, Thomas Cranmer, the former bishop of Worcester, Hugh Latimer, and the bishop of London, Nicholas Ridley, were transported to the supposedly safe location of Oxford to expedite their trials. Their stay in Oxford, however, turned out to be a long one, lasting until their execution by burning outside the Northgate there: Latimer and Ridley on 16 October 1555; Cranmer on 21 March 1556. During the time they spent in Oxford – between nineteen and twenty-four months – they were usually confined apart from one another, in a number of locations, by the municipal officials responsible to the crown for their safekeeping: the mayor and the two bailiffs of Oxford. Cranmer, the most important and politically the most sensitive of the prisoners, appears to have spent most of his long confinement in the Bocardo, the local prison over the town's Northgate next to St Michael's church. Latimer and Ridley, on the other hand, spent considerable time privately boarded in the houses of, respectively, the bailiffs and the mayor, and Ridley, in particular, seems to have been able to maintain regular written and personal contact with their supporters and sympathisers. Their confinement must have put the three reformers, all of them Cambridge graduates, into a variety of contacts with local residents, but records for only two of those relationships have survived, and from diametrically opposite sources.
