The Syrmian Front ( sh, Srijemski front/Sremski front) was an
Axis line of defense during
World War II. It was established as part of the
Eastern Front in late October 1944 in
Syrmia
Syrmia ( sh, Srem/Срем or sh, Srijem/Сријем, label=none) is a region of the southern Pannonian Plain, which lies between the Danube and Sava rivers. It is divided between Serbia and Croatia. Most of the region is flat, with the exce ...

After the
Yugoslav Partisans and the
Red Army expelled the Germans from Belgrade in the
Belgrade Offensive, the retreating
Wehrmacht and the
Croatian Armed Forces used fortifications to protect the withdrawal of German
Army Group E from the
Balkans. With help from their Soviet allies, the
Partisans (by then recognized as the Yugoslav army), joined by
Bulgarian and
Italian forces, fought a difficult winter campaign and finally broke through the front on 12 April 1945.
After the Syrmian front was broken, occupied Yugoslavia was liberated.
Operative background and significance
After the September advance through Romania and Bulgaria in October 1944, The Red Army, together with Yugoslav forces, took Belgrade (central communication node of the
Balkans) in the
Belgrade Offensive. Due to Yugoslav partisan activity, the Yugoslav-Allied
Operation Ratweek
In Occupied Europe during World War II, a co-ordinated assassination offensive against Nazi security forces, codenamed Ratweek, was mounted in January 1944 by the Special Operations Executive (SOE), with the intention of creating confusion and ...

Army Group E troops from Greece. The Red Army decided to exploit this delay and continued to advance with the

From September 1944 to January 1945, Army Group E pushed its way through

, and soon their sole available escape route was in a line between
Sarajevo and
Slavonski Brod. For this reason, it was of vital significance for the Germans to defend the zone around Slavonski Brod, which was threatened by the Soviet-Yugoslav advance through Syrmia. To prevent Army Group E from being cut off, the German South-East command prepared seven successive fortified defense lines between the
Danube and
Sava river from
Ruma to
Vinkovci. The Syrmian Front campaign consisted of Yugoslavian attempts to break through these lines of defense.
Operations

The Syrmian Front saw some of the most difficult fighting in
Yugoslavia in World War II. It lasted for almost six months. As the bulk of the Red Army involved in the Belgrade operation continued their
offensive in Hungary, the Yugoslav Army, accustomed to

, many from freshly liberated regions, were drafted ''en masse'' and sent to the front, and the amount of training they received and their casualty levels remain in dispute.
Although mostly stationary, the front moved several times, generally westward, as the Axis forces were pushed back. The fighting started east of
Ruma and stabilized in January 1945 west of
Šid after the town changed hands due to Axis counterattacks. In late March and early April 1945, Yugoslav Army units mounted a
general offensive on all fronts. The
Yugoslav First Army, commanded by
Peko Dapčević, broke through German
XXXIV Corps defenses in Syrmia on 12 April, quickly capturing the cities of
Vukovar,
Vinkovci, and
Županja, and enabling further advances through
Slavonia toward
Slavonski Brod and
Zagreb in the last month of the war.
The campaign can be divided into four distinct phases:
# The first phase lasted from 24 October to the end of December 1944, and was characterized by slow but steady advancement of Yugoslav and Soviet forces through the seven German fortified lines of defense through fierce battles and heavy losses on both sides.
# In the second phase, from 3 to 26 January 1945, the Germans performed a successful counterattack with the newly arrived forces of
XXXIV Corps of Army Group E, and succeeded in winning back to the Nibelung Line, the main line of defense in Syrmia, while inflicting heavy losses to the Yugoslav Army.
# The third phase was a stalemate period from 26 January to 12 April 1945. In this period both sides only performed limited reconnaissance activities.
# The fourth phase began when Yugoslav forces broke through the German defense lines on 12 April, with heavy German losses and fierce battles and Army Group E retreating.
