The Sirdar had returned from Fashoda before Gregory came back, and had left almost immediately for Cairo. On the day after Gregory's return, he had a sharp attack of fever; the result partly of the evil smells at Gedareh, heightened by the fact that the present was the fever season, in the Blue Nile country.
[Chapter 22]: The Crowning Victory.
It was eight weeks before he recovered, and even then the doctor said that he was not fit for any exertion. He learned that on the 22nd of October, Colonel Lewis, with two companies of the camel corps and three squadrons of Lancers, had started from Omdurman to visit the various villages between the White and Blue Niles; to restore order, and proclaim that the authority of the Khedive was established there. On the 7th of November, following the Blue Nile up, he reached Karkoj, but a short distance below the point at which the navigation of the river ceased. He had come in contact with a portion of Fadil's force, but nothing could be done, in the thick undergrowth in which the latter was lurking; and he therefore remained, waiting for the next move on the part of the Dervish commander, while the gunboats patrolled the Blue river up to Rosaires.
Six weeks passed. His force, and all the garrisons on the river, suffered severely from heat, thirty percent of the troops being down together. The cavalry had suffered particularly heavily. Of the four hundred and sixty men, ten had died and four hundred and twenty were reported unfit for duty, a month after their arrival at Karkoj; while of the thirty white officers on the Blue Nile, only two escaped an attack of fever.
At the end of the month, Colonel Lewis was joined by the Darfur Sheik and three hundred and fifty of his men. He had had many skirmishes with Dervish parties, scouring the country for food, and his arrival was very welcome.
Gregory was recommended to take a river trip, to recover his health; and left on a steamer going up with stores, and some small reinforcements, to Colonel Lewis. They arrived at Karkoj on the 14th of December, and learned that the little garrison at Rosaires had been attacked by the Dervishes.
The fifty fever-stricken men who formed the garrison would have had no chance of resisting the attack, but fortunately they had, that very morning, been reinforced by two hundred men of the 10th Soudanese, and two Maxims; and the Dervishes were repulsed, with considerable loss. Two companies of the same battalion had reinforced Colonel Lewis, who marched, on the day after receiving the news, to Rosaires. The gunboat went up to that point, and remained there for some days.
Gregory went ashore, as soon as the boat arrived, and saw Colonel Lewis, to whom he was well known.
"I am supposed to be on sick leave, sir; but I feel quite strong now, and shall be glad to join you, if you will have me."
"I can have no possible objection, Mr. Hilliard. I know that you did good service with Colonel Parsons, and it is quite possible that we shall find ourselves in as tight a place as he was. So many of our white officers have been sent down, with fever, that I am very short-handed, and shall be glad if you will temporarily serve as my assistant."
