What has happened to Achilles between the death of hector and visit Greek camp?

After the death of Hector, Achilles continued to mourn the loss of his close friend Patroclus. He refused to return to battle and withdrew to his tent. The Greeks, without their greatest warrior, struggled against the Trojans. In an effort to appease Achilles, the Greek leaders, led by Agamemnon, offered him gifts and honours, including the return of Briseis, the woman over whom the conflict between Agamemnon and Achilles had begun.

Despite these attempts, Achilles remained steadfast in his grief and anger. He felt that the Greeks had not done enough to honour Patroclus's memory and that Agamemnon had wronged him. He vowed not to fight until Agamemnon paid a greater price for his actions.

During this time, Achilles spent his days grieving, honouring Patroclus's memory, and competing in athletic contests to distract himself from his pain. He also refused to eat or drink, consumed by his grief and anger.

Ultimately, it was the death of another close friend, Patroclus's cousin Antilochus, that persuaded Achilles to return to battle. Filled with renewed fury and determination to avenge his fallen comrade, Achilles donned his armour and rejoined the fighting. His return marked a turning point in the war, and the Trojans were eventually defeated.
