Mbh 6.69.1c

Then in that fierce battle, the great bowman Sikhandin rushed against those two mighty warriors, viz., Bhishma and Drona who, excited with rage, had (thus) fallen upon the Pandavas. Firmly grasping his bow whose twang resembled the roar of the clouds, that hero, shrouding the very Sun with his arrows, quickly covered his antagonists therewith. The grandsire of the Bharatas, however, getting Sikhandin before him, avoided him, remembering the femininity of his sex. Then, O king, urged by thy son, Drona rushed to battle, desirous of protecting Bhishma in that stress. Sikhandin, however, approaching Drona that foremost of all wielders of weapons, avoided, from fear, that warrior resembling the blazing fire that appears at the end of the Yuga. Then, O king, thy son with a large force, desirous of winning great glory, proceeded to protect Bhishma. And the Pandavas also proceeded, O king, firmly setting their hearts upon victory, and the battle then that took place between the combatants of both armies desirous of victory and fame, was fierce and highly wonderful, resembling that (in days of yore) between the gods and Danavas.”
