Fast cavalry is extremely good at escaping from combat and regrouping. Unlike normal troops, a unit of fast cavalry which chooses to flee as a charge reaction and subsequently rallies at the beginning of their next turn may reform facing in any direction and is free to move during the Movement phase. If the chargers fail to catch the fast cavalry unit which declared flee as a charge reaction then the charge is a failed charge as normal. If the flee move of the fast cavalry does not take them beyond the charge reach of their enemies, the unit is destroyed as normal.
