Jonathan Thomas looks at the history and work of the Salvation Army in Wales as it celebrates 150 years since its first mission to Cardiff, followed later by missions to Merthyr Tydfil, Aberdare and many other towns around Wales. Lieutenant Colonel Jonathan Roberts is the Army's current leader in Wales, and he gives his account of some of the movement's early days, as well as outlining its work today. Captain Canon Kathryn Stowers is the Army's Ecumenical Officer for Wales, and she talks about the organisation's radical views on the empowerment of women - it was women who led the Army's early missions to Merthyr, for example. Professor Paul O'Leary of the University of Aberystwyth has studied street processions in Wales, and explains why evangelising on the streets was such a provocative initiative that challenged Victorian notions of respectability. Historically the Salvation Army's uniform has been a huge part of its identity, but as Jennifer Le Zotte explains, there is more to this than meets the eye: in reusing secondhand clothing there was something challenging about this uniform. Even more intriguing is the special uniform for the so-called 'Slum Sisters' who tended to the needs of the very poor. She describes this as 'cross-class drag'! For many of us the Salvation Army is synonymous with brass bands, and Jonathan visits the band of Canton Cardiff Corps to speak to their bandmaster, and to make his own practical contribution!
