Crockett was a pacifist and, consequently, a conscientious objector. During the War he worked as a cowman on a farm in Hampshire, as a stretcher bearer for the ARP in London and then farmed in Cornwall. He and his wife later joined a Pacifist community in Penwrith, which moved to Herefordshire. After spending many years travelling with a theatrical company, the Crocketts joined the Taena Community, first in the Forest of Dean and then at Whitley Court near Prinknash Abbey, where they converted to Catholicism. Towards the end of his life he was Director of Art at Downside School.
