This first battle gets you into the action quickly, two AH river monitors are up against 3 batteries of Serb 76mm field guns, the Serb guns are spread out along the river but close to the north edge so they can engage the AH as soon as they come onto the map and concentrated their fire on the Kupa. Good shooting by the Serbs early on (dice roll) helped them reduce the Kupa a step and win a minor victory.
