The Battle of Traso was an engagement between the Boundary Republic and United Nations Space Command. The Battle of Traso also has the dubious distinction of being the only large-scale UNSC operational failure during the retaking of Boundary. The defeat was mainly the result of competition for forces by Major General Julia Grodbeck and General William Zawon, the latter of whom was assigned to capture Lesno, the capital of the Boundary Republic. As a result, Zawon received priority over Grodbeck.
