Surat Alley was a trade unionist and political activist who campaigned tirelessly for the rights of Indians – and particularly Indian seamen – in Britain in the 1930s and 1940s. India Office surveillance files record the details of his passport, thus shedding light on his date and place of birth, but beyond this, little is known of his early life in India. Indeed, even his affiliations are disputed, with some describing him as a Bengali and former seamen and others doubting that he was a Muslim. It is likely that he arrived in Britain some time in the early or mid 1930s, and it is known that he married a white woman called Sarah (Sally) Reder, with whom he lived first in London’s East End and later in Glasgow.

While Alley was involved in an extraordinary range of activities and organizations, his struggle for equality for Indian seamen was perhaps his greatest political contribution when in Britain. He held a number of posts in different organizations all of which aimed for the betterment of the pay and employment conditions of lascars. He was Secretary of the Colonial Seamen’s Association, formed in 1935 by black, South Asian and Chinese seamen in reaction to the British Shipping (Assistance) Act. He was also the London representative of Aftab Ali’s All-India Seamen’s Federation. In this latter role, he gave much assistance to lascars striking against their unequal treatment at the beginning of the Second World War. He organized meetings and rallies, distributed leaflets, and listened to the seamen’s grievances. When Aftab Ali called off the strikes, having reached an agreement with the authorities, Alley cooperated with this decision but continued to campaign for the release of lascars from prison and their subsequent re-employment, lobbying the Home Secretary and calling on the TUC for support. Alley gained a reputation among government officials as an agitator and trouble-maker, in spite of their partial reliance on him to negotiate with lascars.

In the early 1940s, Alley wrote pamphlets and issued memos on the appalling conditions of Indian seamen’s hostels in Britain, their lack of compensation and pay when injured during the war, and the insufficiency of their wages. In 1941 he sent his memo titled 'Indian Seamen in the Merchant Navy' to the Shipping Federation, the Indian High Commissioner, the Ministry of Shipping and the Ministry of Labour and National Service, urging their intervention. But the authorities repeatedly stonewalled him, claiming intervention could only come from India. In September 1943, when the All-India Seamen’s Federation was starting to disintegrate, Alley launched the All-India Seamen’s Centre, which was soon merged with Aftab Ali’s India-based India Seamen’s Union. The inaugural meeting, held at British Council House, Liverpool, was attended by ninety seamen and other South Asians, as well as spokesmen from the National Union of Seamen, the International Transport Workers’ Federation, and several other organizations. By 1944 the AISC had branches in London, Glasgow and Liverpool. Alley worked hard for the organization, disseminating information in Urdu and Bengali as well as English, and urging seamen to join in order to better protect their rights and interests. His years of activism did see some small successes, although these were generally credited by the authorities to the ship-owners rather than to Alley himself.

Surat Alley’s political interests extended beyond the concerns of lascars. He was Honorary Secretary of the Hindustani Social Club, an organization committed to the social welfare of working-class Indians in Britain as well as to raising their consciousness of the struggle for Indian independence. In this capacity, he helped to organize a charity performance by Ram Gopal and his troupe at the Vaudeville Theatre in December 1939. Alley was also general secretary of the Oriental Film Artistes’ Union. He was involved with Swaraj House, and in 1943 he helped to set up the Federation of Indian Associations in Great Britain which brought together the middle-class members of Swaraj House with the working-class members of the Indian Workers’ Association. Surveillance reports suggest he was an associate of the revolutionary Udham Singh. Shortly after Singh’s arrest in 1940, Alley’s lodgings were searched. Not just confining himself to Indian organizations, Alley was also an active member of the Communist Party of Great Britain, helping them to gain access to the Indian working classes, and worked as an ARP warden in the Second World War.
