Brave and the Bold, The #18 (1958)

THREAT OF THE ICE KING In their travels across the icy peaks, Jon and his mute companion gain the attention of the wicked Ice King. Jon also must complete the fourth Task of Thor, which his minstrel vaguely writes, is to "awaken a sleeping rose". THE DOUBLE DECOY! Sir Oswald sends the young apprentice Brian to capture the Silent Knight, a seemingly impossible task since Brian and the Knight are one and the same. But then, to Brian's shock, he really does find the Silent Knight and he is brought back to Greystone to be hanged at dawn. Brian can't let an innocent person be executed, so it's up to him, as the real Silent Knight, to make a daring rescue.
