In an attempt to coax Hitler out of his rage, General Alfred Jodl speculated that General Walther Wenck 's XII Army , which was facing the Americans, could move to Berlin because the Americans, already on the Elbe River, were unlikely to move further east. This assumption was based on his viewing of the captured Eclipse documents, which organised the partition of Germany among the Allies.  Hitler immediately grasped the idea, and within hours Wenck was ordered to disengage from the Americans and move the XII Army north-east to support Berlin.  It was then realised that if the IX Army moved west, it could link up with the XII Army. In the evening Heinrici was given permission to make the link-up.
