 Pope Paul III put him in charge of organising assistance for the Pilgrimage of Grace (and related movements), an effort to organise a march on London to install a conservative Catholic government instead of Henry's increasingly Protestant-leaning one.Neither Francis I of France nor the Emperor supported this effort, and the English government tried to have him assassinated.In 1539, Reginald was sent to the Emperor to organise an embargo against England—the sort of countermeasure he had himself warned Henry was possible.
