On this (new as at 17.02.21) page, I feature some of the works that I have researched or am currently researching, accompanied by a short text with some insights from primary sources. Once the page includes five or more works, they will be ordered alphabetically by artist surname.
07 March 2021: Vasily Vereshchagin (Vassili Verestchagin), The Apotheosis of War, 1871
When Vasily Vereshchagin died on 13 April 1904, aboard a Russian battleship involved in the Russo-Japanese war, numerous reports circulated around the world about the death of one of the world’s great painters. On 23 April 1904, The Illustrated London News dedicated a full page to ‘works by Vassili Verestchagin, the great Russian war-painter, drowned on the “Petropavlovsk’.  The journal Brush and Pencil wrote at length about his ‘tragic death’, which would ’cause regret to many readers…whether pro-Japanese or pro-Russian in their sympathies’.  Vereshchagin is much less known today outside of Russia, but during his lifetime and for decades afterward he was celebrated as one of the greatest antiwar artists the world had ever seen.
The Apotheosis of War, perhaps his most famous work today, was described thus in a catalogue accompanying an exhibition of his work at the Waldorf Astoria in New York in 1902:
He is the first Russian painter who has given his countrymen a true impression of war —something besides those official pictures where victory is displayed and never defeat. Even when he paints victory he never separates it from its sadness, its ruin, its misery, its mourning beyond relief. I seem to have always before my eyes, as in a dream, that pyramid of piled-up skulls which he met with somewhere in his wanderings, and of which he has made one of his most striking pictures. He wrote underneath it, “ Dedicated to the Conquerors.” 
Vereshchagin witnessed the harshest realities of war first-hand and Apotheosis summarises his bitterness. Describing his purpose, he wrote that:
Observing life through all my various travels, I have been particularly struck by the fact that even in our time people kill one another everywhere under all possible pretexts, and by every possible means. Wholesale murder is still called war, while killing individuals is called execution. Everywhere the same worship of brute strength, the same inconsistency ; on the one hand men slaying their fellows by the million for an idea often im practicable, are elevated to a high pedestal of public admiration : on the other, men who kill individuals for the sake of a crust of bread, are mercilessly and promptly exterminated and this even in Christian countries, in the name of Him whose teaching was founded on peace and love. These facts, observed on many occasions, made a strong impression on my mind, and after having carefully thought the matter over, I painted several pictures of wars and executions. These subjects I have treated in a fashion far from sentimental, for having myself killed many a poor fellow-creature in different wars, I have not the right to be sentimental. But the sight of heaps of human beings slaughtered, shot, beheaded, hanged under my eyes in ali that region extending from the frontier of China, to Bulgaria, has not failed to impress itself vividly on the imaginative side of my art. 
There is a good general description of the painting on Wikipedia, and a number of contemporary publications available on archive.org
The Petropavlovsk was a Russian battleship, which sank after striking one or more mines near Port Arthur, northeast China,during the Russo-Japanese War (1904-05). Vereshchagin had been invited by its Admiral, Stepan Makarov, to join him on board.

17 February 2021: Otto Dix, War Wounded (Kriegsverletzter), 1922
Though there is no specific date for when this picture was completed, it is known that Otto Dix sold it to the Galerie Nierendorf on 24 July 1922. Stylistically, it is a definite departure from the four Dada-influenced war cripple paintings of 1920, moving towards the bitter realism of his controversial painting The Trench [Der Schützengraben] (1923, lost) and his suite of intaglio prints, The War [Der Krieg] (1924).
Otto Dix, War Wounded (Kriegsverletzter), 1922. Pencil and watercolour on paper, 48.8 x 36.9 cm. Kupferstich-Kabinett (Prints and Drawings), State Art Collections, Dresden.
Left: Otto Dix, Transplantation, Portfolio 4, Print 10, The War, 1924. Etching, aquatint and drypoint, 19.8 x 14.9 cm (sheet size; shown with sheet cropped). Right: Soldier with Facial Injuries, c. 1920/24. Photographer unknown (Hugo Erfurth?). The etching shows that Dix did not reverse his drawing (made either directly on the plate or on paper and then copied to the plate).
This picture is intriguing for several reasons, one of which is the possibility that Dix painted this picture in one of the many special hospitals for wounded veterans of World War I, working directly from one of the patients. The sitter wears a hospital shirt typical of this period and similar to that in the photograph above, which also formed the motif for one of Dix’s etchings in the The War [Der Krieg]. On close inspection, as German researcher Bernhard Maaz notes, all four edges of the sheet of paper are perforated, meaning that the paper is unlikely to have been produced for artistic purposes but possibly as tear-out sheets used for medical records. The sitter’s name is unknown but it may have been known to Dix, who did not name the sitter in order to protect his identity. Alternatively, Dix may have worked from a photograph as he did for the etching in The War. But as a veteran who served thirty-eight months on the battlefields, such injuries were nothing new and Dix may have worked from memory. At this time, facially wounded men were largely unseen by the public and at least until late 1920, were not allowed to own photographs of themselves (Erich Kuttner, 1920). Some of these men remained in hospital for several years after the war, as their horribly painful wounds slowly healed, or slowly killed them. Some remained hidden even from their families. Anarcho-pacifist Ernst Friedrich published his book War against War! [Krieg dem Kriege!] in 1924, which included numerous photographs of the facially wounded, bringing to the fore the immense suffering caused to the human body by industrailised warfare.
Interestingly, the picture was sold by Dix’s widow Martha in 1973 to the surgeon Prof. Dr. Werner Widmaier in Leonberg, who himself had suffered injury during the war.
