" FACT. ON ARRIVAL AT TIANANMEN TROOPS FROM SMR HAD SEPARATED STUDENTS AND RESIDENTS. STUDENTS UNDERSTOOD THEY WERE GIVEN ONE HOUR TO LEAVE SQUARE BUT AFTER FIVE MINUTES APCS ATTACKED. STUDENTS LINKED ARMS BUT WERE MOWN DOWN INCLUDING SOLDIERS. APCS THEN RAN OVER BODIES TIME AND TIME AGAIN TO MAKE QUOTE PIE UNQUOTE AND REMAINS COLLECTED BY BULLDOZER. REMAINS INCINERATED AND THEN HOSED DOWN DRAINS."

This is contradicted by most accounts.

From wikipedia:

"At 4 am, the lights on the Square suddenly turned off, and the government's loudspeaker announced: "Clearance of the Square begins now. We agree with the students' request to clear the Square."[124] The students sang The Internationale and braced for a last stand.[125] Hou returned and informed student leaders of his agreement with the troops. At 4:30 am, the lights relit and the troops began to advance on the Monument from all sides. At about 4:32 am, Hou Dejian took the student's loudspeaker and recounted his meeting with the military. Many students, who learned of the talks for the first time, reacted angrily and accused him of cowardice.[126]

The soldiers initially stopped about 10 meters from the students. The first row of troops took aim with machine guns in the prone position. Behind them soldiers squatted and stood with assault rifles. Mixed among them were anti-riot police with clubs. Further back were tanks and APCs.[126] Feng Congde took to the loudspeaker and explained that there was no time left to hold a meeting. Instead, a voice vote would decide the collective action of the group. Although the vote's results were inconclusive, Feng said the "gos" had prevailed.[127] Within a few minutes, at about 4:35 am, a squad of soldiers in camouflaged uniform charged up the Monument and shot out the students' loudspeaker.[127][126] Other troops beat and kicked dozens of students at the Monument, seizing and smashing their cameras and recording equipment. An officer with a loudspeaker called out "you better leave or this won't end well."[126]

Some of the students and professors persuaded others still sitting on the lower tiers of the Monument to get up and leave, while soldiers beat them with clubs and gunbutts and prodded them with bayonets. Witnesses heard bursts of gunfire.[126] At about 5:10 am, the students began to leave the Monument. They linked hands and marched through a corridor to the southeast,[115][126] though some departed through the north.[126] Those who refused to leave were beaten by soldiers and ordered to join the departing procession. Having removed the students from the square, soldiers were ordered to relinquish their ammunition, after which they were allowed a short reprieve from 7 am to 9 am.[128] The soldiers were then ordered to clear the square of all debris left over from the student occupation. The debris was either piled and burnt on the square, or placed in large plastic bags that were airlifted away by military helicopters.[129][130] After the cleanup, the troops stationed at The Great Hall of the People remained confined within for the next nine days. During this time, the soldiers were left to sleep on the floors and fed a single packet of instant noodles split between three men daily. Officers apparently suffered no such deprivation, and were served regular meals apart from their troops."
