Battle of the Ten Kings

Battle of the Ten Kings () is a battle alluded to in Mandala 7 of the Rigveda (hymns 18, 33 and 83.4-8), the ancient Indian sacred collection of Vedic Sanskrit hymns. It is a battle between Aryans (Vedic Indians) (an "internecine war", as the 1911 Britannica puts it, as opposed to the more frequent accounts of Aryans fighting Dasyus). It took place as Puru tribes, allied with other tribes of the north west India and guided by the royal sage Vishvamitra, oppose the Trtsu (Bharata) king Sudas in battle, but are defeated as was celebrated in a provocative hymn of Sudas' poet and priest Vashista (RV 7.18). K. F. Geldner in his 1951 translation of the Rigveda considers the hymns as "obviously based on an historical event", even though all details save for what is preserved in the hymns have been lost. Further details have been provided in an incisive discussion of this hymn by H.P. Schmidt

Belligerents
The Trtsu are the tribe led by king Sudas. Sudas himself is included in the "ten kings", as the Trtsus are said to be surrounded by ten kings in 7.33.5. But it is not made explicit how this number is supposed to be broken down: if of the tribes mentioned in 7.18, the Turvasas, Yaksuss (pun for Yadu), Matsyas, Bhrgus, Druhyus, Pakthas, Bhalanas, Alinas, Shivas and Visanins are counted, the full number is reached, leaving the  Anavas (7.18.14), the Ajas and Sigrus (7.18.19) and the "21 men of both Vaikarna tribes" (7.18.11) without a king, and implying that Bheda (7.18.19, also mentioned 7.33.3 and 7.83.4, the main leader slain by Sudas), Shimyu (7.18.5), and Kavasa (7.18.12) are the names of individual kings. The Bharatas are named among the enemies in 7.33 but not in 7.18.


 * Alinas: One of the tribes defeated by Sudas at the Dasarajna, and it was suggested that they lived to the north-east of Nuristan, because the land was mentioned by the Chinese pilgrim Hiouen Thsang.
 * Anu: Some place them in the (Ravi) area.
 * Bhrigus: Probably the priestly family descended from the ancient Kavi Bhrigu. Later, they are related to the composition of parts of the Atharva Veda.
 * Bhalanas: Fought against Sudas in the Dasarajna battle. Some scholars have argued that the Bhalanas lived in the Bolan Pass area.
 * Druhyus: Some align them with the Gandhari (RV I 1.126.7).
 * Matsya are only mentioned in the RV (7.18.6), but later in connection with the Śālva.
 * Parsu: The Parśu have been connected by some with the ancient Persians.
 * Purus: one of the major tribal confederations in the Rigveda.
 * Panis: also the name of a class of demons; later associated with the Scythians.

Background
Hymns 7.18 and 7.83 are dedicated to Indra and Indra paired with Varuna, respectively. They thank the deity for helping Sudas to defeat his enemies, while hymn 7.33 is addressed by Vashista's descendants to Vashista, praising him for moving the gods to take Sudas' side by his prayers (Indra preferred Vashista's prayers over those of Pasadyumna, son of Vayata, 7.33.2). They describe him as a son of Mitra and Varuna (7.33.11). The hymn stresses the importance of the priests (Vashista is named along with Parashara and Satayatu) in winning Indra's favour; they had invoked Indra while they had moved away from  "home" (grhāt, 7.18.21)

The situation leading up to the battle is described in 7.18.6: The Turvasas and Yaksus (Yadu), together with the Matsya tribe (punned upon by the rishi by comparing them to hungry fish (matsya) flocking together) appear and ally themselves with the Bhrigus and the Druhyus. Their confederation was further increased by the Pakthas, the Bhalanas, the Alinas, the Shivas and the Visanins (7.18.7), while the Trtsus relied solely on the help of the "Arya's Comrade" (āryasya sadhamāḥ), Indra.

The battle
The battle itself took place on the banks of the Parusni (Ravi). The warriors of Sudas are described as white-robed (shvityanca), wearing hair-knots on the right side of their heads (daksinataskaparda), having flying banners (krtádhvaj) (RV 7.83.2), while the ten kings do not sacrifice (áyajyavaḥ). It appears (7.18.5) that Sudas managed to cross the Parusni safely, while his foes, trying to pursue, were scattered by a flood and either drowned or were slaughtered by Sudas' men:
 * 7.18.9 ''As to their goal they sped to their destruction: they sought Parusni; e'en the swift returned not.
 * Indra abandoned, to Sudas the manly, the swiftly flying foes, unmanly babblers.
 * 7.18.9 They went like kine unherded from the pasture, each clinging to a friend as chance directed.
 * They who drive spotted steeds, sent down by Prsni, gave ear, the Warriors and the harnessed horses. (trans. Griffith)

Kavaṣa and the Druhyu were "overwhelmed by Indra" while still in the water (7.18.10). The slain warriors of the Anu and Druhyus are numbered 6,666 (7.18.14).

In the aftermath of the battle, the Bharatas under Sudas (7.33.6), received tribute from the Ajas, the Sigrus and the Yaksus (= Yadu, 7.18.20), and Indra destroyed the seven fortifications of the enemies, and gave the treasures of Anu to Sudas (7.18.13). 7.18.17 stresses that this was a victory against all odds, compared to a lamb defeating a lion.
