What were the causes of Maratha failure in the third Battle of Panipat?

The causes of failure of Marathas in the third Battle of Panipat were:

1. Ahmad Shah Abdali's forces outnumbered the Maratha forces. According to an estimate Abdali's army had 60,000 soldiers while the Maratha army comprised 45,000.
2. Abdali's troops were better equipped and organised than those of the Marathas. While the Marathas fought with swords and lances, Abdali's troops used muskets.
3. Infighting among the Marathas weakened their side. Some of the Maratha leaders were selfish in spirit and weak in their military tactics. The Afghan troops, on the other hand, worked according to a single plan under strict discipline.
