The Ring was Denethor's last hope of success against Sauron. To think he had already been defeated before even learning of the fate of the Ring Bearer going to Mordor is quite astonishing to claim. He sent Boromir to Rivendell in the hope he may gain support from the Wise to use the Ring in Minas Tirith, did he not?
