The Mallians, realising how small the number of Macedonian cavalry was, chose to stop and fight them. Arrian estimated that there were fifty thousand Mallians at this point. As expert as the Companion cavalry was, Alexander had placed himself in a vulnerable situation. However, the Macedonians formed up and circled around the Mallians, attacking them in the flank and rear. Eventually, the Macedonian light infantry came up, and the Mallians lost heart and fled to the city of Mallians. Alexander followed them to the city, and then rested his columns for the rest of the day.
