On 1 February 1919, tanks and soldiers patrolled the streets of Glasgow after “Bloody Friday” when 20,000 strikers gathered in George Square. By the time the strike ended in early February, up to 10,000 troops had been sent to the city. No Scots troops were deployed, as the government feared they would join the workers if a revolutionary situation had developed in Glasgow. The strike had been called to demand a 40-hour week. After it ended, strikers in the shipbuilding industry negotiated a 47-hour week settlement.
