Leosthenes approached the city and with his army fortified a camp, dug up a deep ditch and constructed a palisade.
Initially, Leosthenes would draw up his forces, and approach the city and directly challenge the Macedonians to battle.
The Macedonians denied this challenge, prompting Leosthenes to launch daily attacks on the walls with his soldiers.
He also built a wall and dug a deep, wide ditch, cutting off all escape routes for the Macedonians.
Leosthenes in an attempt to aid his men, was struck in the head by a stone from a sling shot and so he fainted and was dragged to camp.
