Describe the events that lead to the liberation in Buchenwald according to Elie Wiesel?

Elie spends most of four months at Buchenwald. During that
time his father dies from dysentery. Elie tells us that he felt and cared for nothing
until April. It was in April that the front was approaching. The Nazi's began the
process of liquidating the camp. On April 10  the inmates rose up to overthrow their
captors. The guards had herded the remaining children together with the intent of
murdering them. The prisoners prevented this from occurring. By 6:00 PM the camp
resistance had taken control of the camp. The Germans had put up very little resistance.
The American tanks were at the front gates and liberation was at
hand.
