There were about 95,000 Chinese engaged but only one formation, the 38th, remained a viable fighting unit. The Japanese losses of less than 8,000 reflect their superior training, tactics, equipment and air power. With the monsoon season beginning, the Japanese can be well satisfied with having so rapidly overrun Burma, and with the cutting off of China from surface communications.
