When the whole expeditionary force had been disembarked, Admiral Brueys received orders to take the fleet to Aboukir Bay before anchoring the battle-fleet in the old port of Alexandria if possible or taking it to Corfu. These precautions were made vital by the imminent arrival of the British fleet, which had already been seen near Alexandria 24 hours before the French fleet's arrival. It was wisest to avoid the risks of a naval battle – a defeat could have disastrous results and it was in the force's better interests to go by land, marching at top speed to Cairo to frighten the enemy commanders and surprise them before they could put any defence measures in place.
