Mawsworn Battle Plans

Which is more damaging to the enemy, destroying a contingent of their forces or interrupting their communications? Better yet, what if that communication allows you to best place your forces to ambush their reinforcements? I see you understand. There will be a Mawsworn lieutenant, Voxiferus, traveling from the Maw into Korthia, by way of the northern road. Find them, kill them, and bring me the battle plans.
