detachment which will cross the desert, will partake of the plenty of the hanks of the Nile when they reach them; if they should be certain of having water only, and such forage as their cattle should he able to pick up, I apprehend that the difficulty will become so great that the operation ought not to be attempted. It is impossible that the Mamelukes in Upper Egypt can be neutral in the contest in contemplation — they must take part with the French or with us. If they take part with the French, the army will be in the situation in which I have above described it, enjoying no advantage from having reached the banks of the Nile, excepting water, and probably some forage; and it is needless to point out that if the desert is to be crossed under those circumstances care must be taken not only to send, with the body of troops which will cross, a very large proportion of provisions, but means must be adopted to add to them until the operations of this body shall have given them such a hold of the country as to leave no doubt of their steady supply of provisions.
