Elbing, which signified that the great pincer movement had
succeeded. East Prussia was now severed from the rest of the
Reich, and eight divisions of the Second Army were cut off in
the province, together with the whole of the Fourth Army and
the remains of the Third Panzer Army.
The defenders of Königsberg were pinned down and irre-
trievable, but the Fourth Army in central East Prussia so far
had not been heavily engaged, and its commander, General
Friedrich Hossbach, was now contemplating desperate mea-

On Hossbach's instructions the attack was due to open at
1900 on 26 January. 'It was a night of full moon, and in front
of the divisions stretched a bare and snowy landscape. The
