Britain entered the Crimean War in February 1854, and Gladstone introduced his second budget on 6 March. Gladstone had to increase expenditure on the military and a vote of credit of £1,250,000 was taken to send a force of 25,000 to the East. The deficit for the year would be £2,840,000 (estimated revenue £56,680,000; estimated expenditure £59,420,000). Gladstone refused to borrow the money needed to rectify this deficit and instead increased income tax by half, from sevenpence to tenpence-halfpenny in the pound (from ≈2.92% to ≈4.38%). He proclaimed that "the expenses of a war are the moral check which it has pleased the Almighty to impose on the ambition and the lust of conquest that are inherent in so many nations". By May £6,870,000 was needed to finance the war and introducing another budget on 8 May, Gladstone raised income tax from tenpence halfpenny to fourteen pence in the pound to raise £3,250,000. Spirits, malt, and sugar were taxed to raise the rest of the money needed.
