Operation Doppelkopf

Operation Doppelkopf (Unternehmen Doppelkopf) and the following Operation Cäsar were German counter-offensives on the Eastern Front late in 1944 in the aftermath of the major Soviet advance in Operation Bagration.

The operation's codename was a reference to the German card game Doppelkopf.

Role in the conflict
By the end of July 1944, Russian mechanised forces had reached the Gulf of Riga following their headlong advance in the Kaunas and Shyaulyay Offensive Operations, part of the third and final 'pursuit' phase of the strategic offensive Operation Bagration. The Soviet 2nd Guards Army had exploited a breach between the German Sixteenth Army of Army Group North and the neighbouring Third Panzer Army of Army Group Centre, and communication between them was severed. To the east, the 6th Guards Army attacked towards Riga.

The Oberkommando des Heeres made immediate plans for an offensive to restore the connection between the two Army Groups.

Planning
A number of armoured formations were assembled under Army Group Centre in Courland with orders to attack towards Jelgava (Mitau), cutting off the Soviet spearheads. The XXXX Panzer Corps, with the 7th and 14th Panzer Divisions, the Grossdeutschland Division and the 1st Infantry Division, was assembled at Liepāja / Libau, while the XXXIX Panzer Corps was assembled at Tauragė / Tauroggen.

Wehrmacht

 * Elements of 1st Baltic Front (General Hovhannes Bagramyan)

The offensive
The operation commenced with an attack by the 7th Panzer Division on 15 August towards Kelmė. The main offensive began the following day, but there was strong resistance against the XXXX Panzer Corps from ten Soviet infantry divisions supported by three artillery divisions and anti-tank units.

Von Saucken's XXXIX Panzer Corps opened operations on 18 August. Its left flank, an ad hoc formation under Hyacinth Graf Strachwitz von Groß-Zauche und Camminetz, was preceded by a heavy artillery bombardment from the cruiser Prinz Eugen; forces inside the pocket attacked to link up with Strachwitz's force. Strachwitz reached Sixteenth Army at Tukums by midday.

By 27 August, the corridor between Third Panzer Army and Sixteenth Army had been enlarged to 18 miles in width, though the latter had come under renewed pressure from a fresh Soviet offensive against Riga. The operation had also failed in its more ambitious objectives of retaking Šiauliai or of cutting off the 6th Guards Army threatening Riga.

Operation Cäsar
A second German 'spoiling' attack, to disrupt Soviet plans to separate the two German Army Groups, and with the ultimate objective of striking towards Šiauliai, was planned in mid-September. The main strike force was the reorganised XXXIX Panzer Corps, Third Panzer Amy having been placed under the temporary overall control of Army Group North. The attack began on 16 September, in response to the Soviet Riga Offensive Operation, but by 21 September it had ground to a halt in the face of intense Soviet resistance after having penetrated only a few miles. The German forces then assumed a defensive configuration.

Aftermath
The Red Army attacked again on 5 October, in the Memel Offensive Operation. Five days later, they reached the Baltic Sea and finally cut off Army Group North in what eventually became the Courland Pocket. The German XXVIII Corps was isolated from the remainder of Third Panzer Army in a bridgehead at Memel.
