The first intimation that Napoleon received that the Sultan had declared war with France, was the news that an army from Syria had advanced and established itself at a fort in the desert half-way between the frontier of that country and Egypt. He had, in the interval, endeavoured to make himself familiar with the country. Forts had been erected all round Cairo on heights dominating the town, so that a comparatively small force could overawe the population. He himself paid two visits to Suez. Desaix had pushed the Mamelukes still farther into Upper Egypt; a division had established the French authority at Damietta and Rosetta, and every arrangement was made by which the main body of the army could move away with a fair hope that Egypt would remain quiet during its absence.
