Chapter 505: The Battle of King's City (Part III)

Meanwhile, Lightning, Wendy, Maggie and Hummingbird were executing the final attack before the main offensive.

Because the main artillery of the battleships only fired solid bullets, they were largely ineffective against the personnel and defense facilities on the city wall. Hence, the witches aimed to destroy the first line of defense so as to puncture the enemy's effective strength and open up a safe channel for the general offensive.

This was also the first time that the hydrogen balloon was used in battle.

Unlike the thousand-mile raid five months back, the balloon lifted off from just beside the canal this time, allowing almost everyone to witness the ascent of this colossal object. Under Roland's plan, the hydrogen balloon, which could move anywhere without hindrance, was advanced enough to be used as a short-distance bomber during this era. With the fleet behind it providing logistical support, this earmarked the beginning of the generation of aircraft carrier combat.
