1st Infantry Division (Wehrmacht)

The German 1st Infantry Division, (designated 1.Infanterie-Division in German), was one of the original infantry divisions of the Reichswehr and Wehrmacht and served throughout World War II.

History
Originally formed as the beginning of Germany's first wave of rearmament, the division was first given the title of Artillerieführer I and only later called Wehrgauleitung Königsberg. These names were an effort to cover Germany's expansion of infantry divisions from seven to twenty-one. The division's infantry regiments were built up from the 1.(Preussisches) Infanterie-Regiment of the 1.Division of the Reichswehr and originally consisted of recruits from East Prussia. The unit's Prussian heritage is represented by the Hohenzollern coat of arms that served as the divisional insignia. Upon the official revelation of the Wehrmacht in October 1935, the unit received its title of 1.Infanterie-Division. In February 1936, the headquarters of the division was moved from Insterburg to Königsberg.

With the German invasion of Poland in September 1939, the 1st Infantry Division advanced toward Warsaw as a component of the XXVI Army Corps in von Küchler's 3rd Army. It engaged Polish forces near the heavily-defended town of Mława (see Battle of Mława) for several days, then crossed over the Bug and Narew Rivers. It fought again near Węgrów and Garwolin and ended the campaign east of Warsaw.

Playing a minor role in the invasion of France, the division returned to East Prussia in the autumn of 1940. With the launch of Operation Barbarossa, the 1st Infantry Division entered the Soviet Union as part of the 18th Army with Army Group North, advancing on Leningrad. It remained and fought in the area of Leningrad and Lake Ladoga through December 1943. (See Siege of Leningrad.) Transferred to the 1st Panzer Army, the division fought at Krivoy Rog and broke out of encirclement in March 1944.

The 1st Infantry Division returned to its native East Prussia for the last time in the summer of 1944. Except for participating in the urgent and temporary link-up with the now-isolated Army Group North in Lithuania (Operation Doppelkopf), the unit remained to defend the easternmost German province from the advancing Red Army. Alternating between 3rd Panzer and 4th Armies, the division was trapped in the Königsberg/Samland area after it was cut off from the rest of Germany by the end of January, 1945.

At 0400 hours on February 19, 1945, elements of the 1st Infantry, led by a captured Soviet T-34 tank, spearheaded a westward offensive from Königsberg intended to link with General Hans Gollnick's XXVIII Corps, which held parts of the Samland peninsula, including the vital port of Pillau. Capturing the town of Metgethen, the unit opened the way for the 5th Panzer Division to join with Gollnick's forces near the town of Gross Heydekrug the next day. This action re-opened the land route from Königsberg to Pillau, allowing for the evacuation of civilian refugees via the port and solidifying the German defense of the area until April.

With the capitulation of Königsberg on April 9, 1945, the surviving elements of the division retreated to Pillau, where this East Prussian unit clung to the last ground of its home province until surrendering to the Soviets.
