The assault on Gal began in the early hours of December 21, marking the final deadline set by Ding Zhennan.
According to Liu Zunshan's suggestion, three days prior on December 18, the Eleventh Marine Division deployed a reinforced regiment, with fire support provided by the Thirty-First Special Mixed Fleet, to launch an amphibious landing near Kakinad, north of the River Mouth Delta at the Godavari River Estuary.
To draw the attention of the Fan Army, the Navy dispatched dozens of transport ships, mostly civilian freighters.
Additionally, the landing fleet heading north passed by the landing grounds outside Kakinad and stayed for a day, but did not take part in landing operations.
Due to the lack of resistance from the Fan Army, the Marine Corps secured the beachhead in just one day, then spent two days expanding inland.
By late night on the 20th, the Marine Corps had pushed the front line to the outskirts of Kakinad.
