During May the preparations for the advance on the Dervish position at Firket continued, and towards the end of the month it became evident that they were nearly complete. The steady accumulation of stores at Akasha had turned that post into a convenient base from which the force might operate for a month without drawing supplies of any kind from the north. The railway, which had progressed at the rate of about half a mile a day, had reached and was working to Ambigole Wells, where a four-gun fort and entrenchment had been built. The distance over which convoys must plod was reduced by half, and the business of supply was doubly accelerated. By degrees the battalions and squadrons began to move forward towards Akasha. Sarras, deprived of its short-lived glory, became again the solitary fort on a crag. Wady Halfa was also deserted, and, except for the British battalion in garrison, could scarcely boast a soldier. Both the Egyptian battalions from Suakin had arrived on the Nile. The Xth Soudanese were on their way. The country beyond Akasha had been thoroughly reconnoitred and mapped to within three miles of the Dervish position. Everything was ready. The actual concentration may be said to have begun on the 1st of June, when the Sirdar started for the front from Halfa, whither he had returned after the cavalry skirmish. Construction work on the railway came to a full stop. The railway battalions, dropping their picks and shovels, shouldered their Remington rifles and became the garrisons of the posts on the line of communications. On the 2nd of June the correspondents were permitted to proceed to Akasha. On the 3rd the Xth Soudanese passed through Ambigole and marched south. The Horse battery from Halfa followed. The Egyptian battalions and squadrons which had been camped along the river at convenient spots from Ambigole to Akasha marched to a point opposite Okma. Between this place and the advanced post an extensive camp, stretching three miles along the Nile bank, arose with magic swiftness. On the 4th the 7th Egyptians moved from Railhead, and with these the last battalion reached the front. Nine thousand men, with ample supplies, were collected within striking distance of the enemy.
