Describe the ensuing battle. What does Jupiter promise June on behalf of the Ausonians?. Ancient History

Aeneas returns to the battle and the tide of the battle turns in the favor of Aeneas and Turnus several times. Then,  eneas realizes that Latinus' city is unguarded and advances toward it.

Turnus hears cries of suffering in the city and rushes back to see what is wrong. Turnus calls for Aeneas and himself to duel one on one as they had agreed to do that morning to spare the suffering of his people. The two prepare to duel, but realizing the battle's inevitable outcome, Juno asks Jupiter for the Trojans to adopt the language of the Latins, to which he obliges. Aeneas then wounds Turnus in the leg and kills him in the name of Pallas.
