 Garnet 's first few years in England were spent meeting new priests in London , including John Gerard and Edward Oldcorne . Jesuits had been banished from England since 1585 , and if discovered they risked being charged with high treason . Avoiding pursuers was therefore a recurrent problem , and Garnet was almost caught on several occasions . As a result of an almost disastrous meeting at Baddesley Clinton in 1591 , when he and many others were almost captured together while renewing their vows , he reorganised the mission into eleven smaller groups , each assigned two weeks annually . Following Southwell 's capture in June 1592 , and the search of Anne Vaux and Eleanor Brooksby 's rented house in Warwickshire , he wrote to Acquaviva to ask for an assistant who could succeed him as superior . Henry Walpole was thus dispatched , but was captured on his arrival in December 1593 , and executed in York in April 1595 . Garnet believed that it was his duty to observe ( in disguise ) the executions of his fellow priests , so as to secretly administer the last rites , and he may have been present at Southwell 's execution at Tyburn in 1595 . The latter 's death was a significant blow for Garnet , who later wrote of the " intolerable burden of loneliness " he carried while in England .
