 The Chinese forces advanced in three large groups, and fiercely assaulted our positions in front of Ky Lua.Facing greatly superior numbers, short of ammunition, and exhausted from a series of earlier actions, Colonel Herbinger has informed me that the position was untenable and that he has been forced to fall back tonight on Dong Song and Thanh Moy.All my efforts are being applied to concentrate our forces at the passes around Chu and Kép.
