'Hamburg' (i) was a German operation in the rear area of General Heinrich Clössner’s 2^nd Panzerarmee against partisans in the region of Slonim near Baranovichi to the south-west of Minsk in the Belorussian region of the German-occupied western USSR (10/21 December 1941).

The partisan activities were as yet relatively small in scale compared with their vigour and impact in the following years, but even at this time the Germans were acutely conscious of the threat thus posed to their extended lines of communication across the western USSR at the time of severe winter conditions and the unfolding of the Germans' desperate effort to reduce Moscow before the arrival from Siberia of fresh troops highly experienced in and equipped for the conduct of winter operations.
