Operation Doppelkopf (German: Unternehmen Doppelkopf) and the following Operation Cäsar were German counter-offensives on the Eastern Front in the late summer of 1944 in the aftermath of the major Soviet advance in Operation Bagration with the aim of restoring a coherent front between Army Group North and Army Group Centre. The operation's codename was a reference to the German card game Doppelkopf.

Strategic situation

By the end of July 1944, Soviet mechanised forces had reached the

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 severed the connection between them. German counter-attacks failed to restore it, and significant elements of the German armed forces were left isolated.

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

Grossdeutschland Division and the 1st Infantry Division, was assembled at Liepāja / Libau, while the XXXIX Panzer Corps was assembled at Tauroggen.^[2]

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.^[2]

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;^[3] forces inside the pocket attacked to link up with Strachwitz's force. Strachwitz reached Sixteenth Army at Tukums by midday.^[4]

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.^[5] 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, was planned to destroy Bagramyan's forces in the salient below Riga and push the front out to a straight line between the Segewold position and Šiauliai.

Riga Offensive Operation, but by 19 September it had ground to a halt in the face of intense Soviet resistance after having penetrated only a few miles.^[6]

The German forces then assumed a defensive configuration.

Aftermath

The Red Army attacked again on 5 October, in the

Memel Offensive Operation.^[8] Five days later, they reached the Baltic Sea and finally cut off Army Group North in what eventually became the Courland Pocket.^[9] The German XXVIII Corps was isolated from the remainder of Third Panzer Army in a bridgehead at Memel.^[9]
