Fortress front Oder-Warthe-Bogen - Festungsfront Oder-Warthe-Bogen

The Fortress front Oder-Warthe-Bogen, also Fortress in the Oder-Warthe-Bogen, popular East wall called, was a strongly fortified defense line built by the German Reich in mid-1934, about 120 km east of Berlin from the river Warthe in the north to the Oder in the south.

history

Central section plan

The construction of this plant could be started at this early point in time (1934), since the German Reich was not subject to any contractual restrictions in the east, as it was in the west by the Versailles Peace Treaty was the case. Taking into account the delivery times for the armor, the construction time was estimated at seven years, the costs for the entire project should amount to 600 million Reichsmarks.[1]

The east wall was planned as a 110 km long, fortified area with a depth of two to three kilometers, much like it was a few years later Siegfried Line was also carried out. Some of the bunker constructions are therefore very similar to those of the Siegfried Line, while others are much more extensive. The fortress front consists of numerous bunkers and hydraulic engineering facilities such as B. Dams and moats. Roads that led through the so-called main battlefield were provided with armored barriers, swing bridges and tipping roller bridges - tipping roller bridges made it possible to tilt the bridge body and roll it into a space below the road.

Since the political situation had changed in 1939 so that the protection of the imperial border to the west was classified as more urgent, the expansion of the fortress front Oder-Warthe-Bogen was stopped. Fortress construction personnel and armored components were diverted to the west in favor of an accelerated expansion of the western wall. Of the planned 160 structures, only about 60 were completed. With the construction of the Atlantic Wall, weapons and communications equipment began to be dismantled in 1942.[1]

The focus of the east wall is the central section, which begins in the south with the so-called Burschener Loop near the village Burschen (Polish: Boryszyn) and extends from there about twelve kilometers to the north. In the central section, the bunkers are connected to one another by a system of underground tunnels (hollow passages). The main lines of this tunnel system were bombproof and designed for single-track light rail traffic and pedestrian traffic in double rows. The track systems were built by the Bochumer Verein für Gußstahlfabrikation AG (BVG). In this underground system there are train stations, workshops, machine rooms and barracks. The total length of the underground system is around 32 km.

In 1944, the war situation made it necessary for the Fortress front restore. So until January 1945, inter alia. as part of the Company Barthold as well as through the Reich Labor Service Field positions excavated, wire obstacles and several ring stands erected. This made it possible to build a continuous fire front for machine guns.[1]

On January 28, 1945, the first attack on the central section, which the Red Army broke through in the area of ​​the Tirschtiegelstellung after three days. Also on other sections, such as B. the group of works Ludendorff and in the southern areas around Möstchen, there was considerable resistance. Recent research shows that the front withstood three days here as well. Only through a bypass movement north of the road Meseritz−Hiking and north of Schwiebus the front could be overcome. Some tank factories were "ignored" by the Red Army; Volkssturm men entrenched there were only asked to surrender between April and May. Because not everyone followed the instructions, the tank works were destroyed without being cleared.

Buildings

The fortress front consists of structures that were combined into 13 groups of works. A Group of works describes a network of systems under uniform management, which are also often connected with hollow passages. The connection was prescribed according to the Army Service Regulations HDV g4, but not consistently implemented in the Oder-Warthe-Bogen fortress front.

Central section

Boy loop

The Boy loop(Pętla Boryszyńska) is the southernmost part of the central section of the fortress front near the place Boryszyn (Guys). The unfinished bunkers or tank works of tank battery 5 are located in the Burschener Loop. The tank works are connected to one another by an underground system of tunnels, stations, workshops and ammunition stores. From the Burschener Loop, the underground system extends about 12 km to the north.

The Scharnhorst group of works is located in the center of the central section of the Oder-Warthe-Bogen fortress front two kilometers west of the village of Kalawa (Poland) and is a well-known group of works of the defense system, as official tours through the bunker and tunnel system of the Oder-Warthe-Bogen fortress front are here and the condition of the facilities is excellent. The group of works consists of the armor works 716a, 716 and 717. Originally the construction of the B armor works (1.50 m wall thickness) 716, 717, 718, an A1 welding works (2.50 m wall thickness) A-5 and the Armored battery 5 in thickness A (3.50 m wall thickness). In fact, only two armored works, 716 and 717, were built. In addition, armored works 716a was built, which was not included in the original plans. The construction of the planned tank battery 5 was started, but not completed. In the course of restoring the defensive capabilities of the facilities on the Oder-Warthe-Bogen fortress front, ring stands of type 58c were built in the area of ​​the Scharnhorst work group in 1944. Directly in front of the tank works is a hump line with an anti-tank ditch.

- The group of works “LUDENDORFF” was part of the Nischlitz-Obra line before it was included in the fortress front Oder-Warthe-Bogen. At that time it originally consisted of a main structure to which two objects of approximately equal strength were connected with hollow passages and is enclosed on three sides by the Obra river. These three works all had the number 522. These three works were also incorporated into the fortress front Oder-Warthe-Bogen (FFOWB) and received new numbers. The two-storey "main plant" (construction period 1935–1936) in the expansion stage B old (1.50 meter wall thickness) was given the number 865. A three-story plant was connected to it 3-notch turret for machine guns (2 P7) with number 867 and one Pak-Casemate for 3.7 cm pack (29 P8) with 3-notch turret for machine guns (2 P7) with the number 866. Plant 865 had one 6-notch tower for 2 machine guns (20 P7) and two notch plates (10 P7) to defend the two entrances. The connecting corridors consist of precast concrete parts 0.5 meters in length.
The other works were only created later in the course of the expansion of the fortress front. These are the works 868 and 863 connected to the entrance structure 864 (machine grenade launcher M19 in armored tower 424 P01, armored tower for infantry observation 52 P8, Schartenplatte 7 P7) as well as a combat post for a 4.7 cm Pak (t), which the channel 820 could brush in the longitudinal direction. The construction time for these objects can be set at 1937–1938. The single-storey plant 868 housed an armored turret for artillery observation (21 P7). Plant 863 was a four-story combat block with a 3-notch turret for machine guns (2 P7). In these newer structures, the connecting ducts are cast in concrete. This group of works was also permanently blown up, but the tank turret of the M19, a tank turret 2P7 and the bedding of the anti-tank gun can still be found here. A MG notch plate 403 P9 is said to be at the entrance to 868.
