what did ajax do as a result of his defeat to get the arms

The armor led to a dispute between Ajax and Odysseus. Both heroes felt entitled to it. To settle the matter, the Greeks decided to take a vote, and they awarded the armor to Odysseus.

Enraged by this decision, Ajax planned an assault on the Greek troops that night. However, Athena, the goddess of wisdom, drove Ajax temporarily insane, and he attacked a flock of sheep instead. After recovering his senses, he was so ashamed that he killed himself with the sword Hector had given him.
