However, in 1882 a nationalist revolt occurred in Egypt, headed by Colonel Urabi. There was a perceived danger to the Suez Canal, and therefore British communications with its to Indian empire, as well as to British holders of Egyptian bonds. At first, Gladstone appealed to the Concert of Europe to take collective action, although this was met by unenthusiastic responses. France initially sent warships to join the Royal Navy at Alexandria, but refused to send military forces in fear of weakening its defences against Germany. On 10 July Gladstone instructed that an ultimatum be given to Urabi to halt military fortifications of Alexandria within twelve hours. Urabi did not answer and so on 11 July the Royal Navy bombarded the city while the French withdrew. This resulted in rioting and Gladstone got from Parliament £2,300,000 and raised the income tax from 5"d". to 6½"d". to finance a military campaign. The decision to go to war met with opposition from within the Liberal Party, and the Radical MP John Bright resigned from the Cabinet in protest. On 19 August British troops commanded by Sir Garnet Wolseley landed at Port Said and on 13 September defeated Urabi's forces at the Battle of Tel-el-Kebir. On hearing news of the British victory Gladstone was ecstatic and ordered salutes of the guns in Hyde Park in their honour.
