When Agamemnon calls an assembly of the army and says they should leave Troy, who does he blame?

Because Achilles sulks in his tent, his Achaean comrades suffer in their epic conflict with Troy. No matter how many times the Achaeans try to persuade Achilles to join the battle, he pointedly refuses to emerge from his tent. It is a desperate situation, and Agamemnon has made an important decision. He calls together an assembly of the Achaeans. The mood is somber, and morale is low as Agamemnon begins to speak. The grief-stricken king tells the assembled throng that the Achaeans should return home. Having been driven back to their ships by the rejuvenated Trojans, it is clear that the Achaeans are not favored by the gods. If the gods are against them, then there is nothing to do but head home. In particular, Agamemnon says that Zeus, the father of the gods, has turned against them.
