Akshauhini


An akshauhini is described in the Mahabharata as a battle formation consisting of 21,870 chariots ; 21,870 elephants ; 65,610 horses and 109,350 infantry. Thus one akshauhini consisted of 218,700 warriors. The ratio is 1 chariot: 1 elephant: 3 cavalry: 5 infantry soldiers. In each of these large number groups, the digits add up to 18.
It is mentioned in the Mahabharata that in the Kurukshetra War the Pandava army consisted of seven akshauhinis, and the Kaurava army had eleven akshauhinis.

The Pandava army is a coalition of 7 akshauhinis, primarily the Panchala and Matsya forces, the Rakshasa forces of Bhima's son, Ghatotkacha and Vrishni–Yadava heroes.
The 4 types of units that make up an akshauhini can also be seen in Chaturanga, the predecessor of chess.
