Co-operative trading had been rooted in Woolwich and the Royal Arsenal since the mid 18th century. In 1868 the Royal Arsenal Supply Association was established by William Rose (1843–1909?) and Alexander McLeod (1832–1902), consisting of 20 workers from the Royal Arsenal. The first base and store was at Rose's house at 11 Eleanor Road (now Barnard Close). In 1869 Rose was laid off at the Arsenal and emigrated to Canada (where his son William Oliver Rose became a well-known politician). McLeod took over as secretary and moved the store to Parry Place (Spray Street Quarter). The society adopted the Rochdale Principles of profit-sharing and renamed itself Royal Arsenal Co-operative Society in 1872.
