Demetrius, though he had thus easily driven Pyrrhus out of his kingdom, did not despise him. He had determined to go to war on a great scale to recover his father's throne, with a force of a hundred thousand men and five hundred ships of war; and he did not wish to be thwarted in this design by Pyrrhus, or to leave him as a fierce and dangerous neighbour for Macedonia. Consequently, as he had no leisure to go to war with him, he wished to come to terms with him and make peace, so that he might be at liberty to attack the other kings. These considerations led him to conclude a truce with Pyrrhus. However, the greatness of the force at Demetrius's disposal now led him to assume such an arrogant tone that the other kings were alarmed and sent letters to Pyrrhus in which they expressed their surprise that he should overlook the magnificent opportunity which Demetrius would offer him by engaging in a foreign war, and asked him whether, when he was able to drive that restless intriguer out of Macedonia, he intended not to do so, but to sit idle at home while Demetrius gained wealth and power, until at length he would have to fight for his hearth and home in Molossia, and that too when Demetrius had just deprived him of Korkyra by means of his wife. For Lanassa had quarrelled with Pyrrhus because he paid too much attention to his barbarian wives, had retired to Korkyra, and, as she still wished to be a queen, invited Demetrius to take possession of her person and of the island. He at once proceeded thither, married Lanassa, and placed a garrison in the city.
