Other volunteers from Britain had volunteered to become involved almost immediately following the military rising, such as Nat Cohen and Sam Masters, two clothing workers from London on a cycling holiday in Spain. With three other British volunteers, Richard Kisch, Tony Willis and Paul Boyle, they participated in an abortive raid on Mallorca, in which Kisch was badly injured. On their return to Barcelona, the group became the Tom Mann Centuria, under the command of Nat Cohen.
