text_A: Apollo played a pivotal role in the entire Trojan War. He sided with the Trojans, and indirectly sent a terrible plague to the Greek camp, which led to the conflict between Achilles and Agamemnon. He killed the Greek heroes Patroclus, Achilles, and numerous Greek soldiers. He also helped many Trojan heroes, the most important one being Hector. After the end of the war, Apollo and Poseidon together cleaned the remains of the city and the camps.
