Ashwatthama vs Bhima

Endued with great energy and prowess, the son of Kunti, in
consequence of his extreme lightness of hand, within the twinkling of an eye, covered Aswatthaman
with a shower of weapons. Then Drona's son, smiling at the rushing Bhima and addressing him (in
proper words) covered him with arrows, inspired with mantras and equipped with blazing points.

Shrouded with those shafts that vomited fire and resembled snakes of blazing mouths, as if covered with
sparks of gold. The form, O king, of Bhimasena in that battle looked like that of a mountain in the
evening when covered with fire. That weapon of Drona's son, directed against Bhimasena increased in
energy and might, O king, like a conflagration assisted by the wind.
