This originated in the 1940s as a development of the activities of the 'Kingswood Preachers' under the leadership of Donald Soper, who was for many years its President. A mission in Dorking in August 1942 was characterized by 'high spirits and Christian dedication' and was followed in subsequent years by similar week-long missions in Barnstaple, Salisbury and Plymouth. In November 1946 the label of 'London Christian Campaigners' was changed to 'Order of Christian Witness' in recognition of the widening scope of the movement. The Anglican report Towards the Conversion of England was an important influence. A mission in Huddersfield in 1947, at the invitation and with the support of the Free Church Federal Council, marked a turning point in several respects. The movement's growth called for its original organization to be improved and Harry Morton was appointed General Secretary for two crucial years. Experience of industrial mission in the work-place as well as in the open air led to the adoption of the policy of 'infiltration', in which mass witness was complemented by conversation with individuals. There was a combined emphasis on both the 'social gospel' and personal salvation. The movement was formally wound up in the autumn of 1996 with a service of thanksgiving at Hinde Street Church, London.
