'Martin' (ii) was the German operational plan, developed as an alternative to 'Herbstnebel' (i), devised by the headquarters of the Oberbefehlshaber 'West', Generalfeldmarschall Gerd von Rundstedt (autumn 1944).

'Herbtnebel' (i) was rejected by Adolf Hitler as being too conservative, and on 1 November 1944 Hitler opted for 'Martin' (ii), which was developed for implementation as 'Wacht am Rhein'.
