On 10th July, at mid-day, several hundred Baris, having cautiously approached the grazing cattle unobserved, made a sudden rush from the bushes upon the guards, killing one soldier and wounding another. The soldiers belonged to the line, and must have behaved badly, as the musket and cartouche-box and belt were stolen and carried off from the dead man. The shots from the guard immediately alarmed the camp. The horses were saddled, and, attended by Lieutenant Baker, I rode hard in pursuit. The natives had gained the forest and had scattered, but we rode a red-painted savage to bay, who fought to the last, shooting two arrows at me, which I avoided by dropping quickly on my horse's neck, and a third arrow stuck deeply in Mr. Baker's saddle as he escaped the well-aimed shot by spurring his horse across the line of sight. These arrows were shot at a distance of a very few yards. The native was killed. On 12th July the Baris attempted to surprise both my station and the camp at head-quarters. On the 13th the natives repeated the attempt; but one was shot dead by the sentry at Gondokoro; also another met the same fate at my station. Nearly every night we were subject to attempts at surprise. This was excellent practice for the troops, as it taught them the, necessity of keeping a good look-out; at the same time it was very wearying, as the men had to work hard all day, and they were kept awake at night. The Baris were irrepressible vermin that gave us no rest. My men were all occupied in building the station, therefore it was impossible for me to take a flying column and give the Baris a severe lesson; but I made up my mind that when the work should be finished, I would take the fight out of them most thoroughly. They now considered us fair game, that they might insult as they thought proper; and I heard from our two faithful allies, Sherroom and Morgian, that they imagined we should become afraid of them, and then return to Khartoum. They teased us at night like rats, but they lost many men. I rather admired them for their persistence, as the scouts must have been adventurous fellows. Whenever these people were taken prisoners, they confessed that they were the spies of the main body that was concealed at some distance in the rear. The favourite method of a Bari attack is during the night, when the darkness reduces the danger of fire-arms. On such occasions they generally halt either in forest or high grass, according to circumstances, about half a mile from the camp they propose to attack. Scouts are sent forward to ascertain the position and vigilance of sentries before the advance of the main body. The scouts, being quite naked, crawl upon their hands and knees until the darkness permits them to approach within a few yards of the sentries. They then lie flat upon their bellies unobserved until they can retreat to the expectant body in their rear.
