{{lang|de|Aufmarsch II Ost}} was for the contingency of an isolated Russo-German war, in which Austria-Hungary might support Germany. The plan assumed that France would be neutral at first and possibly attack Germany later. If France helped Russia then Britain might join in and if it did, Italy was expected to remain neutral. About {{nowrap|60 per cent}} of the German army would operate in the west and {{nowrap|40 per cent}} in the east. Russia would begin an offensive because of its larger army and in anticipation of French involvement but if not, the German army would attack. After the Russian army had been defeated, the German army in the east would pursue the remnants. The German army in the west would stay on the defensive, perhaps conducting a counter-offensive but without reinforcements from the east.{{sfn|Zuber|2010|pp=54–55}} {{lang|de|Aufmarsch II Ost}} became a secondary deployment plan when the international situation made an isolated Russo-German war impossible. {{lang|de|Aufmarsch II Ost}} had the same flaw as {{lang|de|Aufmarsch I Ost}}, in that it was feared that a French offensive would be harder to defeat, if not countered with greater force, either slower as in {{lang|de|Aufmarsch I Ost}} or with greater force and quicker, as in {{lang|de|Aufmarsch II West}}.{{sfn|Zuber|2010|pp=52–60}}
