On the tenth day, the Pandavas, unable to withstand Bhishma's prowess, decided to put Shikhandi, who had been a woman in a prior life, in front of Bhishma, as Bhishma has taken a vow not to attack a woman.
Shikhandi's arrows fell on Bhishma without hindrance.
Arjuna positioned himself behind Shikhandi, protecting himself from Bhishma's attack and aimed his arrows at the weak points in Bhishma's armor.
Soon, with arrows sticking from every part of his body, the great warrior fell from his chariot.
His body did not touch the ground as it was held aloft by the arrows protruding from his body.

The Kauravas and Pandavas gathered around Bhishma and at his request, Arjuna placed three arrows under Bhishma's head to support it.
Bhishma had promised his father, King Shantanu, that he would live until Hastinapur was secured from all directions.
To keep this promise, Bhishma used the boon of "Ichcha Mrityu" (self-wished death) given to him by his father.
After the war was over, when Hastinapur had become safe from all sides and after giving lessons on politics and Vishnu Sahasranama to the Pandavas, Bhishma died on the first day of Uttarayana.
