"The Military Commission has decided to convene an emergency enlarged meeting and has asked the principally responsible comrades of all major units to attend. The main aim is to make one an-nouncement: that the present situation in Beijing is still chaotic. Although martial law has been declared, some of the martial law tasks have in fact not been carried out. Some army units enforcing martial law have been blocked, and they have not forced their way through in order to avoid direct confrontation. Through great effort, most units have now entered their predetermined positions.The situation was even more chaotic a few days ago. No vehiclebearing a military plate could pass through. Is this state of affairs still not a disturbance? The situation in the capital is precisely adisturbance. This disturbance has not subsided."
