The Japanese attacked the first of the three Chinese defensive lines, but were repeatedly turned back by the dug-in troops and their heavy machine-gun fire.

Both sides suffered heavy losses, but in the end, the Japanese managed to breach the Chinese first line of defense.

The Chinese inflicted heavy casualties on the Japanese armored forces, destroying approximately half of the tanks and killing the infantry behind them with small-arms fire.

On March 24, the Japanese launched an all-out assault on the Chinese, throwing in all of their remaining planes, tanks, and infantry.

After reevaluating the situation, Japanese tacticians concluded that they could not afford to suffer any more losses from what was considered to be an inconclusive battle about the trivial matter of a Chinese headquarters, and on 1 April, they began to withdraw.
