Fort Chi-Kuan had no artillery parapet.
Thus on the north front, from Chi-Kuan battery to Sung-Shu, a distance of about two miles, there were three permanent forts and seven semi-permanent works and batteries.
The fighting was of the utmost severity, and continued through the 22nd; and although the stormers captured the two forts they were absolutely unable to make any further progress under the fire of the permanent forts Erh-Lung and Chi-Kuan on either side of, and the Wan-tai fort behind, Pan-Lung.
From this time forward there was a desperate struggle at the sapheads on the north front .2 On the 26th of October another assault was made on Chi-Kuan A particular feature of these constant night-fights was the effective use of the defenders' searchlight, not only to show up the enemy but to blind him.
At Chi-Kuan, the counterscarp gallery had been breached by an ill-managed Russian mine on the 23rd of October and the Japanese got in through the breach and made a lodgment.
On the 22nd of November the Japanese assaulted the trench round Chi-Kuan battery.
They held most of the ditch of Chi-Kuan Fort and were cutting down the escarp, and two parallels had been made only 30 yds.
At Chi-Kuan Fort the terreplein of the fort had been covered with entanglements defended by machine guns on the gorge parapets, and the Japanese could make no way.
The escarp of Chi-Kuan was blown up, and at the cost of 800 men, General Sameyeda (11th division), personally leading his stormers, captured the great fort on the 19th of December.
