The emperor visited the grave of Luther, and when urged to dishonor his remains, replied-- "I war not with the dead, but with the living.

Let him repose in peace; he is already before his Judge." The Landgrave of Hesse Cassel, now the only member of the Protestant league remaining in arms, was in a condition utterly hopeless, and was compelled to make an unconditional submission.
The landgrave, ruined in fortune, and crushed in spirit, was led a captive into the imperial camp at Halle, in Saxony, the 19th of June, 1547.

He knelt before the throne, and made an humble confession of his crime in resisting the emperor; he resigned himself and all his dominions to the clemency of his sovereign.

As he rose to kiss the hand of the emperor, Charles turned contemptuously from him and ordered him to be conveyed to one of the apartments of the palace as a prisoner.
Most ignobly the emperor led his two illustrious captives, the Elector of Saxony and the Landgrave of Hesse Cassel, as captives from city to city, exhibiting them as proofs of his triumph, and as a warning to all others to avoid their fate.

Very strong jealousies had now sprung up between the emperor and the pope, and they could not cooperate.
