By the beginning of 1759 neither alliance had the advantage, in either the land or sea campaigns, and both were having serious problems financing the war. In 1759 more than 60 per cent of French revenue went to service its debt, causing numerous shortages. The French Navy in particular was overstretched and suffered from the lack of a coherent doctrine, exacerbated by the inexperience verging on incompetence of the secretary of state for the navy, Nicolas René Berryer, a former chief of police. Meanwhile, Britain's war effort up to early 1757 had been a failure, with setbacks in Europe, North America, India and at sea. From June it came under the control of the assertive new secretary of state for the southern department (foreign minister), William Pitt, who imposed a coordinated strategy. By early 1759 this was beginning to bear fruit.
