One of the most successful insurgent attacks was made on 11 July on a party of 35 Japanese infantrymen who were conveying supplies by boat from Taipei to Tokoham. The Japanese were ambushed, and although they fought bravely, all but one of the party were either killed or so badly wounded that they committed suicide rather than fall alive into the hands of the enemy. The Japanese pursued the insurgents and defeated them on 12 July in an engagement at Long-tampo.
