Having fulfilled their object, which was to retain Mahmud at Metemmeh by showing him that, if he advanced against Merawi and Dongola, we had it in our power to occupy the town; and so cut off his retreat, and prevent reinforcements or stores from reaching him from Omdurman, the gunboats returned to Berber.

So far, Gregory had had no duties to perform in his capacity of interpreter, for no prisoners had been taken. On the way down the river, one of the artillery sergeants explained the working of the Maxim to him, taking the weapon to pieces, and explaining to him how each part acted, and then showing him how to put it together again. The sergeant having done this several times, Gregory was then told to perform the operation himself, and the lessons continued after their arrival at Berber.

In the course of a week he was able to do this smartly; and had learned, in case of a breakdown, which parts of the mechanism would most probably have given way, and how to replace broken parts by spare ones, carried up for the purpose.

There was no long rest at Berber, and on the 1st of November the gunboats again went up the river, reinforced by the Metemmeh, which had now arrived. Each boat, as before, carried fifty soldiers; and Major Stuart-Wortley went up, as staff officer. The evening before starting, they received the welcome news that the railway line had, that day, reached Abu Hamed.

This time there was but a short pause made opposite Metemmeh, and after shelling the forts, which had been added to since the last visit, they proceeded up the river. Shortly after passing the town, a large Dervish camp was seen in a valley, and this, they afterwards found, was occupied by the force that had returned from Berber. A heavy fire of shell and shrapnel was opened upon it, and it was speedily destroyed.

The gunboats then went up as high as the sixth cataract. The country was found to be absolutely deserted, neither a peasant nor a Dervish being visible. Having thus accomplished the object of their reconnaissance, the flotilla returned, exchanged fire with the Metemmeh batteries, and then kept on their way down to Berber.

[Chapter 11]: A Prisoner.

Rather than remain unoccupied on board the gunboat, Gregory went to Colonel Wingate's headquarters and said that he should be very glad if he would allow him, while the flotilla remained at Berber, to assist in interrogating the fugitives who arrived from the south, and the spies employed to gain early information of the intentions and movements of the enemy. The position of the Dervishes at Metemmeh was becoming critical. The Khalifa was desirous that Mahmud should return with his force to Omdurman, there to take part in the battle in which, as he was convinced, the invaders would be annihilated. Mahmud, who was of an eager and impetuous disposition, was anxious to take the offensive at once, and either to march upon Merawi and Dongola, or to drive the British out of Berber.

There could be no doubt that his view was a more sagacious one than that of his father; and that the best tactics to be adopted were to harass the British advance, fall upon their convoys, cut their communications, and so oblige them to fall back for want of supplies. The Khalifa's mistake was similar to that made by Theodore in Abyssinia, and Koffee Kalkalli in Ashanti. Had either of these leaders adopted the system of harassing the invaders, from the moment they left the coast, it would have been next to impossible for the latter to arrive at their destination. But each allowed them to march on, unmolested, until within striking distance; then hazarded everything on the fortune of a single battle, and lost.

Mahmud made no movement in obedience to the Khalifa's orders to retire to Omdurman, and the latter thereupon refused to send any further supplies to him, and Mahmud's army was therefore obliged to rely upon raids and plunder for subsistence. These raids were carried out with great boldness, and villages situated within a few miles of Berber were attacked. The Dervishes, however, met with a much warmer reception than they had expected, for rifles and ammunition had been served out freely to the villagers; and these, knowing the fate that awaited them were the Dervishes victorious, offered so obstinate a resistance that the latter fell back, discomfited.
