The Army began To Seal off The Square From Reinforcements of Students and Residents

At about 1:30 am, the vanguard of the 38th Army and paratroopers from the 15th Airborne Corps arrived at the north and south ends of the Square, respectively. They began to seal off the Square from reinforcements of students and residents, killing more demonstrators who were trying to enter the Square. Meanwhile, the 27th and 65th Armies poured out of the Great Hall of the People to the west and the 24th Army emerged from behind the History Museum to the east. The remaining students, numbering several thousand, were completely surrounded at the Monument of the People's Heroes in the center of the Square.
