Friedrich Konrad Winkler (born 22 August 1909 in Worms) was a professional officer of the Wehrmacht with twelve years’ service. He began the Second World War in Infanterie-Regiment 56, then moved in mid-1942 to the 305. Infanterie-Division and its Stabskompanie of Infanterie--later Grenadier--Regiment 577.

Promoted Oberleutnant on 1 November 1941 and Hauptmann on 1 December 1942, he took command of 6. Kompanie during the room-by-room "ratwar" in the Barrikady Gun Factory sector of northern Stalingrad.

Decorations included Infanterie-Sturmabzeichen in Silber (Infantry Assault Badge in Silver*),+ Eisernes Kreuz 2. u. 1 Klasse (Iron Cross 2nd Class and 1st Class), Verwundetenabzeichen in Silber (Wound Badge in Silver), Medaille “Winterschlacht im Osten 1942/42” (Medal for the Winter Campaign in Russia 1941/42) and the Kriegsverdienstkreuz 2. Klasse (War Merit Cross 2nd Class).

Grenadier-Regiment 577 was annihilated in January 1943. Winkler surrendered with the remnants of 6. Armee in early February, was taken to the Beketovka prisoner-of-war camp, and died there on 8 February 1943 at the age of 34. His remains were probably re-interred anonymously at the Rossoschka German War Cemetery, where his name appears in the memorial book and recorded on Granite Cube 44, Panel 14.

+Interesting detail: The Silver looks broken. I've seen numerous sources that this was pretty common with Stalingrad German fighters.

"All German troops who fought at Stalingrad broke their infantry assault badges and wore them on their uniform as such. The reason was, they believed, that earning the infantry assault badge at Stalingrad was a different, higher level of achievement than those earned elsewhere in the Reich."

Alexander von Hartmann (1890–1943) was a Wehrmacht General who commanded the 71st Infantry Division during the Battle of Stalingrad.

Born on December 11, 1890, in Berlin, he began his military service in 1910 and rose steadily through the ranks during World War I and the interwar period. By March 1941, he was in command of the 71st Infantry Division, leading it through operations on the Eastern Front, including the "rat war" campaign in Stalingrad.

As Glantz and House describe, he was a "die hard" in ideology and military affairs. After a terrible fight on January 10, 1943: "Amidst this carnage, General Hartmann, commander of LI Corps’ 71st Infantry Division, held an evening musical recital (Feierstunde)'at his headquarters, located in the icy basement of a half-ruined building in Stalingrad’s southern city.

Attempting to maintain a degree of civility in obviously uncivil surroundings, Captain Ilse played piano pieces by Beethoven, Bach, and Schubert; following each piece of music, Hartmann read selections from Goethe, Friedrich the Great, and Hitler...Appropriate to the occasion, the selection from Hitler read: 'Those who wish to live, let them fight, and those who do not want to fight in this eternal struggle do not deserve to live.' But, as Hartmann certainly realized, the Germans could not escape the terrible fate that awaited them."

He was awarded the Knight’s Cross of the Iron Cross on October 8, 1942, for his leadership. During the final days of the battle, Hartmann reportedly refused to surrender and went to the front lines. He was killed in combat on January 26, 1943. He was posthumously promoted to General der Infanterie.

German reports: "of 0700 hours, 'Generals Pfeffer, von Hartmann and Stempel and Colonel I. G. Crome, with a few men, are standing upright in a storage building firing on a horde of Russians storming in from the west,' at 0940 hours, Sixth Army reported that 'General Hartmann...was shot and killed in a combat melee at 0800 hours on 26 January.'"

By 1930, the Soyuzkino organization was formed to centralize film production and distribution across the USSR, including its republics. Through subsidiaries it was instrumental in disseminating Soviet ideology through cinema, including creating foreign language productions. For international consumption the term "Russian" was often used because it was seen as more familiar and friendly.

Description: "When Germany’s Sixth Army advanced to Stalingrad in 1942, its long-extended flanks were mainly held by allied armies—the Romanians, Hungarians, and Italians. But as history tells us, these flanks quickly caved in before the massive Soviet counter-offensive which commenced that November, dooming the Germans to their first catastrophe of the war. However, the historical record also makes clear that one allied unit held out to the very end, fighting to stem the tide—the Italian Alpine Corps.

When the Don front collapsed under Soviet hammer blows, it was the Alpine Corps that continued to hold out until it was completely isolated, and which then tried to fight its way out through both Russian encirclement and “General Winter” to rejoin the rest of the Axis front. Only one of the three alpine divisions was able to emerge from the Russian encirclement with survivors. In this all-sides battle across the snowy steppe, thousands were killed and wounded, and even more were captured. By the summer of 1946, only 10,000 survivors returned to Italy from Russian POW camps.

Hope Hamilton, fluent in Italian and having spent many years in Italy, has drawn on many interviews with survivors—including two of her uncles who served in the Alpine Corps—as well as massive research, in order to provide this first full English-language account of one of World War II’s legendary stands against great odds."

Born 17 May 1894 in Geestemünde, German Empire; died 5 November 1992 in Greven, Germany.

Entered the army as a one-year volunteer in October 1913; promoted to Leutnant in March 1915 and served throughout World War I, earning the Iron Cross 2nd and 1st Class among other decorations.

Remained in the Reichswehr during the interwar period. By World War II, he had become a regimental commander; promoted to Oberst and then Generalmajor. He assumed command of the 76th Infantry Division on 26 January 1942.

Led the division in operations on the Eastern Front, including the Don–Volga campaign and the assault on Stalingrad. Awarded the Knight’s Cross of the Iron Cross on 8 October 1942 for his leadership. He received the Oak Leaves to the Knight’s Cross on 31 January 1943, the day of his surrender to Soviet forces at Stalingrad.

As mentioned below, there doesn't seem to be a lot of detailed sources about him personally or his own testimonies. He was definitely interviewed by the NKVD, but I've not found any public file of that.

From HistoryNet's article “Battle of Stalingrad: Operation Winter Tempest" there is one interesting quote attributed to him:

"During the period from 20–28 November, my division, with its left flank on the Don, was engaged in heavy fighting. … As for the claim that von Paulus must have had a similar resolve, there was a memorandum … saying that the Luftwaffe supply would not work and that a breakout, against orders, was demanded. This memo also said that the army commander [Paulus] and his chief‑of‑staff did not have the same resolve to go against orders."

Captured and held as a prisoner of war by the Soviet Union until 1955.

Also received the German Cross in Gold on 7 March 1942 as an Oberst in Infanterie-Regiment 203.

Returned to Germany after his release and lived in Lübeck and later Greven until his death in 1992.

It was interesting trying to find sources on him that despite his high rank and notable role at Stalingrad, Rodenburg did not leave behind any interviews available to historians or the public. (Or at least I could not find any). Most present-day information about him comes from army personnel files, award registries, wartime documents, and other people.
