rioters; in contrast, many in the Labour Party, which was linked to the trade unions, regarded him as having been too heavy-handed. In consequence of the latter, Churchill incurred the long-term suspicion of the labour movement. Asquith called a general election in December 1910 and the Liberals were re-elected with Churchill secure in Dundee. In January 1911, Churchill became involved in the Siege of Sidney Street; three Latvian burglars had killed several police officers and hidden in a house in London's East End, which was surrounded by police. Churchill stood with the police though he did not direct their operation. After the house caught fire, he told the fire brigade not to proceed into the house because of the threat posed by the armed men. Afterwards, two of the burglars were found dead. Although he faced criticism for his decision, he stated that he "thought it better to let the house burn down rather than spend good British lives in rescuing those ferocious rascals". In March 1911, Churchill introduced the second reading of the Coal Mines Bill in parliament. When implemented, it imposed stricter safety standards at coal mines. He also formulated the Shops Bill to improve the working conditions of shop workers; it faced opposition from shop owners and only passed into law in a much emasculated form. In April, Lloyd George introduced the first health and unemployment insurance legislation, the National Insurance Act 1911; Churchill had been instrumental in drafting it. In May, Clementine gave birth to their second child, Randolph, named after Churchill's father. In response to escalating civil strife in 1911, Churchill sent troops into Liverpool to quell protesting dockers and rallied against a national railway strike. During the Agadir Crisis of April 1911, when there was a threat of war between France and Germany, Churchill suggested an alliance with France and Russia to safeguard the independence of Belgium, Denmark and the Netherlands to counter possible German expansionism. The Agadir Crisis had a profound effect on Churchill and he altered his views about the need for naval expansion. First Lord of the Admiralty In October 1911, Asquith appointed Churchill First Lord of the Admiralty, and he took up official residence at Admiralty House. He created a naval war staff and, over the next two and a half years, focused on naval preparation, visiting naval stations and dockyards, seeking to improve morale, and scrutinising German naval developments.
