01 Invasion

nder orders from Caliph Abu Bakr, Khalid invades Mesopotamia, amassing an army of 18,000 volunteers. At the Battle of the Chains, the Persians chain themselves together to bolster their lines, but Khalid outmanoeuvres them. Further north, at the Battle of the River, he and his champions kill three Persian generals, before destroying an army twice his size.
