Operation Herbstnebel (i)

'Herbstnebel' (i) was a German unrealised plan by the Oberkommando der Wehrmacht for Generalfeldmarschall Albert Kesselring’s Heeresgruppe 'C' in Italy to make a strategic withdrawal from its current positions in northern Italy first to the line of the Po river and then to the planned 'Voralpen-Stellung' in the southern approaches to the Alps (September 1944).

The plan was designed to provide Generaloberst Heinrich-Gottfried von Vietinghoff-Scheel’s 10th Army and General Joachim Lemselsen’s 14th Army with positions which could be held more easily, economise on manpower, and simplify the German logistical situation in the face of rampant Allied air power over northern Italy, but was flatly rejected by Adolf Hitler. The plan was subsequently revised and authorised by von Vietinghoff-Scheel, now elevated to command of Heeresgruppe 'C', as 'Herbstnebel' (iii) in the spring of 1945.
