First stage
In order to determine the enemy position and number as well as terrains, the JSDF sent UGV to scout the area first. When the UGV drone came beyond the Gate in Alnus Hill, they were able to scout the area and the numbers of Imperial Troops around Alnus Hill that including retreating troops from Ginza and reinforcement from the capital.
During the scouting, most Imperial Soldiers or Auxillary troops hesitated to attack the drone since they were clueless about what it was due to the massive gap in technology between the Empire and Japan.
Second stage
After the scouting was completed, the JSDF sent a battalion of tank and armored vehicles to assault Imperial's position in Alnus Hill. The reinforcement Imperial's army and the retreating army from Ginza commanded by Senator and Mage Godasen at the time were completely overwhelmed and helpless against the superior firepower of machine guns and tanks of the JSDF and their primitive weapon like arrows, ballistic or catapult were completely useless against the modern steel plates of tank and armored vehicle of the JSDF.
As the result, the whole Imperial military camps and army were being decimated after two days of futile fighting. Only Godasen and few troops made back Sedera alive with massive injuries.
After cleaning up the corpse of Imperial troops, the JSDF began to set up permanent base in Alnus Hill. While setting up defense to fight the Allied army in the Second Battle of Alnus Hill.
