In front of the lines running north and south, and distant about 1,100 yards, was a formidable outwork standing on rising ground. This was a polygonal redoubt, and mounted six guns. In the rear of this redoubt and on the lines was a 4-gun battery, behind which was a look-out and telegraph station, the wire running back to Arabi's head-quarters near the railway station, and in the midst of a large camp. The diminished size of the ditch from this point northwards is very noticeable. The attack was evidently hoped for at and near the railway.

Following the lines in a northerly direction, the next battery was at the intersection of the two lines of intrenchments. This was the most elaborately finished of all the redoubts, and mounted five guns. Still further in the same direction was another formidable battery of five guns.[58] Beyond this there were two other incomplete redoubts, further still to the northward, but this part of the line was hardly begun.

As regards the east and west line, intersecting the lines running north and south, its object was to afford a defence in the event of the enemy succeeding in breaking through those lines at the northern end, their weakest part.[59]

To the eastward of the lines and in the direction of Kassassin was a tolerably level desert with smooth sand and pebble.

The information, received from spies and prisoners, was to the effect that the enemy's force at Tel-el-Kebir consisted of from 60 to 70 guns, twenty-four battalions of infantry (18,000 men), and three regiments of cavalry, together with about 6,000 Bedouins, besides a force of 5,000 men with 24 guns at Salahieh,[60] all under the immediate command of Arabi himself.

The general character of the ground lying between the two armies was that of gently undulating, pebbly slopes, rising gradually to an open plateau from ninety to a hundred feet above the valley through which the railway and canal ran. To have marched over this plateau upon the enemy's position by daylight, the British troops would have had to advance over a glacis-like slope, absolutely without cover, in full view of the enemy, and under the fire of his artillery, for about five miles. Such an operation would have entailed heavy loss from an enemy with men and guns protected by intrenchments from any artillery fire which the attacking force could have brought to bear upon them. To have turned the Egyptian position, either by the right or left, was an operation which would have entailed a wide turning movement, and, therefore, a long, difficult and fatiguing march, and moreover would not have accomplished the object Wolseley had in view, namely, that of grappling with the enemy at such close quarters that he would be unable to shake himself free, except by a general fight of all his army. The object was to make the battle a final one, whereas a wide turning movement would probably only have forced Arabi to retreat upon the cultivated country in his rear, where, the land being irrigated and cut up in every direction by deep canals, it would have been difficult for a regular army to follow him. Influenced by these considerations, and also by the information that the enemy did not push his outposts far beyond his works at night, Wolseley determined upon the difficult operation of a night march, to be followed by an attack on the Egyptian position before daylight.

As soon as it was dark on the evening of the 12th September, the camp at Kassassin was struck, and all the tents and baggage were stacked alongside the railway. The camp fires were left burning. The troops then moved into position near a spot described as "Ninth Hill." There they formed in order of battle and bivouacked—no fires were allowed, even smoking was prohibited, and all were ordered to maintain the utmost silence.[61]

The formation of the troops was as follows:—

On the right, the 1st Division, commanded by Lieutenant-General Willis, and consisting of two brigades, viz., the 2nd, under Major-General Graham, in front, and the 1st, or Guards Brigade, under the Duke of Connaught, in the rear; on the left, the 2nd Division, commanded by Lieutenant-General Sir Edward Hamley, and consisting of two brigades, viz., the 3rd, or Highland Brigade, under Major-General Sir Archibald Alison, in front, and the 4th, under Lieutenant-Colonel Ashburnham, in the rear. Between the two Divisions was placed the Artillery Brigade under Brigadier-General Goodenough. On the extreme right was the Cavalry Division under Major-General Drury-Lowe, and on the extreme left, under Major-General Sir Herbert Macpherson, were the Indian Contingent and the Naval Brigade.

At 1.30 on the morning of the 13th, the order was given for the advance of the 1st and 2nd Divisions simultaneously, and the celebrated march on Tel-el-Kebir began. The Indian Contingent and the Naval Brigade did not move until an hour later, to avoid giving the alarm to the enemy, by the passing of the force through the numerous villages in the cultivated land south of the Canal.
