Turn 4 began with revolt in the Eastern Sudan. Trinkitat and Kassala were ungarrisoned and fell immediately. Suakin was unmolested and its entire garrison marched southward to Tokar, intent on liberating Trinkitat. No enemy forces were encountered along the way.
In the Western Sudan, X/IV and 2/5 continued their advance on El Obeid. They were attacked in their camp by one unit of dervish spearmen, one unit of cavalry, and one unit of mixed rifles and spears. The dervish rifle unit worked its way into protective ground within range of the zeriba while the remaining ansar kept out of sight. A lengthy rifle duel then broke out, with the dervishes initially dishing out a lot more punishment than they took. Cochinos Bey, commanding X/IV, was wounded in one of the early rounds of firing, and the officer of the 2/5 was killed a short time later. Eventually, however, the Egyptians' advantage in quantity of rifles began to be felt. After eight rounds of fire (during which the Egyptians never once got the first shot of the turn!) the dervishes were reduced to a mere three riflemen. At that point they finally failed a critical morale test and withdrew. The spearmen and cavalry then initiated their charge against another side of the zeriba. Suddenly the Egyptians' dice, which had been stone cold in the duel against the jehadia, turned red hot. In three rounds of firing the two dervish units were reduced to only 10 figures between them and both failed morale checks before anyone could breach the zeriba. The Egyptians' luck continued after the battle, too, as six of seven wounded men recovered, including Cochinos Bey. Afterward, however, the two units together could muster only 24 riflemen, one officer, and one NCO, and the occupied town of El Obeid still sits between them and the river.
After his hard-won victory last turn, Manila Bey was understandably upset when handed his orders from Khartoum- he was to remain in Berber with his command and hold out for as long as possible. He watched from the ramparts as Safieh, Bordein, and the men of the 2/2 Egyptian infantry steamed away up the river.
The gunboats encountered no resistance from the dervishes still presumed to be watching Berber. At Atbara they were challenged by a single gun, which killed the NCO of Bordein's bluejackets and one of Safieh's gunners before being silenced. At Metemmeh they were again opposed by a single dervish cannon, which killed one of the Egyptian soldiers aboard the barge and KO'd Bordein's deck gun (repairable at Khartoum). Both boats managed to claw their way through the 6th cataract. At Wad Hamed, a third dervish cannon nearly sank Safieh with a critical hit at the waterline, but the flooding was stopped in time to avert disaster. Two crewmembers wounded in these fights recovered. The boats are poised to re-enter Khartoum next turn, bringing whatever badly-needed supplies they scraped up on their danger-filled journey.
Two more units arrived at Aswan, the X/VI Sudanese and the 5/4 Egyptian Artillery (Nordenfeldt gun).
At the end of turn 4, the revolt index in the Northern and Southern Sudan remained topped out at 10. In the west it dropped to 3, but in the east it rose to 5. The Mahdi earned 60 more VPs, lifting his score to 189- 47% of the way to victory! If Khartoum falls now, the loss of its 25 VPs could throw the game to the prophet very quickly. Recapturing El Obeid would help the Egyptians tremendously, and the revolt index in the west is low enough to put the town within reach for Cochinos Bey and his weakened force, with a bit of luck. With a little more luck, they might even quell the revolt in the west before any help can reach them- it's just barely possible.
