Fall Weiß (1943)
Encyclopedia
The Battle of the Neretva (Croatian
, Serbian
, Bosnian
, Slovene Bitka na Neretvi), codenamed Fall Weiss, was a German
strategic plan for a combined Axis
attack launched in early 1943 against the Yugoslav Partisans throughout occupied Yugoslavia
during the Second World War
. The offensive took place between January and April 1943. It is named after the nearby river, the Neretva
.
The operation is generally known as the Fourth anti-Partisan Offensive, while it is also known as the Fourth Enemy Offensive (Croatian
, Serbian
, Bosnian
Četvrta neprijateljska ofenziva/ofanziva, Slovene četrta sovražnikova ofenziva) or the Battle for the Wounded (Bitka za ranjenike) in ex-Yugoslav sources.
, six German and three Italian
, as well as two Croatian divisions and a number of Chetnik and Ustasha formations. Estimated 150,000 Axis combatants engaged a much smaller partisan force.
The operation was carried out in three stages:
During the battle, the Partisans were caught in a pocket with their backs to the Neretva
river. On their - western - side, were German forces, including several elite units and supported by panzer brigades. The eastern side (opposite the Partisan pocket) was guarded only by Chetnik
formations, who were acting in coordination with the Germans. To reach this side the Partisans would have to cross one or more of the five bridges on the Neretva river. If the Partisans could cross the river they would be relatively safe; however, they had insufficient time to cross as the Axis forces were preparing for their final push.
In order to counter this strategic "checkmate
", the Partisan commander, Marshal Josip Broz Tito
, prepared an elaborate deception. He ordered his sappers to actually blow up all the bridges on the river. When air reconnaissance brought this information to the German command, they concluded that the Partisans must be preparing a final dash north of their current position (along the western shore of the Neretva), and had blown up the bridge to prevent desertion as well as attack by Chetnik forces from the other side of the river. They thus began a redeployment of troops in the area to block the anticipated movement.
This redeployment gave the Partisan engineers precious time needed to sufficiently repair the bridge and to eliminate the Chetnik troops defending its far side. The Germans, characteristically, quickly caught on, but were unable to correct their mistake and prepare a serious attack in time, because of their previous redeployment orders. With their rearguard fighting off an increasingly powerful German advance, the Partisans crossed the river under intense air bombardment (the Axis deployed large Luftwaffe
formations), but the mountainous landscape prevented accurate destruction of the makeshift bridge. After the escape was complete, the weak bridge was finally rendered useless to prevent pursuit. The humiliating strategic defeat was amplified by Tito being able to keep his well known pledge not to leave the wounded behind, as they faced certain execution at the hands of the Axis (which later actually happened in the aftermath of the Battle of the Sutjeska).
, capturing another two thousand. Despite these heavy losses and a tactical victory for the Axis powers, the partisan formations secured their command and the hospital, and were able to continue operations. In fact, once they reached the eastern parts of Bosnia and Herzegovina
, the Partisans had to face only the Chetniks, and in turn almost entirely incapacitated them in the area west of the Drina
river.
The next major operation in Yugoslavia was Operation Schwarz.
The 1969 Oscar-nominated motion picture The Battle of Neretva
