The Bilin was not a proper defensive position, and the division tried to retreat over the Sittang River. Air attacks, poor organization and vehicle breakdowns delayed the division, and Japanese parties infiltrated around them to threaten the vital bridge over the Sittang. The division's commander, Major General "Jackie" Smyth VC, was forced to order the bridge to be destroyed, with most of the division cut off on the far side of the river.
