In reality, Emery had never even once planned to leave his side of battle to the so-called chance. The stake placed on the table was simply too big to leave things on the probability that the enemy would or wouldn't attack them.
Hence, from the very beginning, he had prepared the strategies and the surroundings used to its best, to boost his prospect of winning to the utmost capacity. He decided not to explain his tactic in detail so that both Arthur and Gwen would not be worried.
In addition, there was still the possibility of spies within their ranks. Therefore, only his closest confidant and related personnel knew about the plan.
Before they arrived at the eastern battlefield, Emery told Galahad and his fifteen hundred archers to bring as many arrows as they could possibly bring. Thus, one could blatantly see the hundreds of piles of arrows lying in the camp. Moreover, he was the one who directed when and where the Demetea archers shoot their arrows.
