Ashwatthama arrows

Then all great car-warriors, O king, pierced Drona's son unitedly and separately with many shafts,
whetted on stone equipped with wings of gold. The youthful prince of the Chedis pierced Drona's son with twenty
and Partha pierced him with three. Then Drona's son struck Arjuna with six arrows, and Vasudeva with
six, and Bhima with five, and each of the other two viz., the Malava and the Paurava, with two arrows.
