Nana Sahib decided to use these prisoners for bargaining with the East India Company. The Company forces, consisting of around 1,000 British, 150 Sikh soldiers and 30 irregular cavalry, had set out from Allahabad, under the command of General Henry Havelock, to retake Cawnpore and Lucknow. The first relief force assembled under Havelock included 64th Regiment of Foot and 78th Highlanders (brought back from the Anglo-Persian War), the first arrivals of the diverted China expedition, 5th Fusiliers, part of the 90th Light Infantry (seven companies), the 84th (York and Lancaster) from Burma, and EIC Madras European Fusiliers, brought up to Calcutta from Madras. Havelock's initial forces were later joined by the forces under the command of Major Renaud and Colonel James Neill, which had arrived from Calcutta to Allahabad on 11 June. Nana Sahib demanded that the East India Company forces under General Havelock and Colonel Neill retreat to Allahabad. However, the Company forces advanced relentlessly towards Cawnpore. Nana Sahib sent an army to check their advance. The two armies met at Fatehpur on 12 July, where General Havelock's forces emerged victorious and captured the town.
