The force to be employed was to be chiefly drawn from the Army of Occupation in Egypt, and General Stephenson was instructed by telegraph to make the necessary preparations. He was informed that the object of the expedition was to relieve the Tokar garrison if it could hold out, and, if not, to take any measures necessary for the safety of the Red Sea ports. He was to select the three best battalions under his command, and these, with the Royal Irish Fusiliers (then on their way from India), the York and Lancaster Regiment from Aden, and a battalion of Marines, were to form an infantry brigade. The garrison of Alexandria was to be removed to Cairo while the expedition lasted, and orders were sent to the fleet to hold Alexandria temporarily. The 10th and 19th Hussars, the Mounted Infantry, and any trustworthy native horsemen at Souakim, were to constitute the mounted force. The 19th Hussars were to be mounted with native horses taken from the Egyptian cavalry under Sir Evelyn Wood. The baggage was to be on the lowest possible scale, as the troops were to be back in Cairo in three weeks. Tents were to accompany the force to Souakim or Trinkitat, as the case might be. The greatest publicity was to be given to the determination to relieve Tokar by British soldiers. Messages were despatched to the garrison at Tokar, urging them to hold out, as relief was on the way, and the expedition was hurrying forward with all possible speed. The command of the expedition was given to Major-General Sir Gerald Graham, who had led the Second Brigade at Tel-el-Kebir. Generals Davis and Redvers Buller were to accompany him. Every effort was made to send off the expedition as early as possible. The troops from Egypt embarked at Suez and proceeded to Souakim and Trinkitat. Between the 16th and 18th February the 10th and 19th Hussars, two batteries of Royal Artillery, the 3rd Battalion of the 60th King's Royal Rifles, the 42nd Royal Highlanders (Black Watch), the 75th Gordon Highlanders, the 65th York and Lancaster Regiment, the 89th Royal Irish Fusiliers, the 26th Company of the Royal Engineers, and 100 Mounted Infantry left for the scene of operations. Detachments of Marines from the vessels of the Mediterranean Squadron were also told off to accompany Graham's force. The reorganized Egyptian Army under Sir Evelyn Wood was anxious to take part in the expedition, but the British Government had declined to sanction this, on the ground that the Egyptian army was expressly raised for the defence of Egypt proper, excluding the Soudan. General Graham left Suez with his head-quarters on the 18th February and proceeded to Souakim.
