The Battle of Harren's Ford became the Battle of the Eastern Plain on the ninth day, when both commanders committed everything.
Aldrath's decision was the decision of a general who understood that the ford battle's attrition was unsustainable and that the only path to the decisive engagement that his numerical superiority required was the open-field battle where forty thousand soldiers could bring their weight to bear simultaneously rather than feeding units into the ford's constrained terrain where the Horde's defensive advantages negated the numbers.
