At Erh-Lung on the 20th of November three mines were exploded, which half filled the ditch, and the Japanese later on sapped across to the escarp over the debris.
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.
The escarp of Ehr-Lung was also blown up, and the ruins of the fort were stormed by the 9th division on the 28th of December, though a mere handful of the defenders prolonged the fighting for eight hours and the assailants lost loon men.
