Crito
The dialogue takes place in Socrates' prison cell, where he awaits execution. He is visited before dawn by his old friend Crito, who has made arrangements to smuggle Socrates out of prison to the safety of exile. Socrates seems quite willing to await his imminent execution, and so Crito presents as many arguments as he can in order to persuade Socrates to escape. On a practical level, Socrates' death will reflect badly on his friends--people will think they did nothing to try to save him. Also, Socrates should not worry about the risk or the financial cost to his friends; these they are willing to pay, and they have also arranged to find Socrates a pleasant life in exile. On a more ethical level, Crito presents two more pressing arguments: first, if he stayed, he would be aiding his enemies in wronging him unjustly, and would thus be acting unjustly himself; and second, that he would be abandoning his sons and leaving them without a father.
Hippocrates of Athens
While marching back towards Athens with his soldiers, the Boeotians arrived. A battle, known as the Battle of Delium, took place between the Athenians and the Boeotians, between Delium and Oropus. The Athenians were clearly defeated. Hippocrates died near the beginning of the battle and nearly a thousand Athenians were slain alongside him. Only nightfall prevented further losses. After a siege of seventeen days, Delium fell to the Boeotians and at that point the bodies of Hippocrates and the other men were returned to the Athenians.
