Alexander rapidly dressed himself the moment he got the news, donning his armor and kit, before kissing his wife and the three girls goodbye, and then riding out with his bodyguards to the camp as soon as possible.
The cold spring air brushed past him as he completed the short journey without incident, and was quickly ushered inside.
"They have started marching my lord," Menes was there to greet Alexander around the gates, and he then heard his boss say, "Have the soldiers take their meals. We will move out in an hour."
Alexander had constructed defensive structures prior to the battle a kilometer ahead of the camp and he intended to face the enemy there.
"Yes, my lord," Menes was already doing this so, and so soon the pre-battle meals were consumed, and the grand total of 42, 143 people moved out of their camp, leaving only a small rear guard consisting of mostly slaves and servants to guard the camp's possessions.
