of Saxony, Dresden not only had garrisons but a whole military borough, the Albertstadt. This military complex, named after Saxon King Albert, was not specifically targeted in the bombing of Dresden, though it was within the expected area of destruction and was extensively damaged. During the final months of the Second World War, Dresden harboured some 600,000 refugees, with a total population of . Dresden was attacked seven times between 1944 and 1945, and was occupied by the Red Army after the German capitulation. The bombing of Dresden by the Royal Air Force (RAF) and the United States Army Air Forces (USAAF) between 13 and 15 February 1945 was controversial. On the night of 13–14 February 1945, 773 RAF Lancaster bombers dropped 1,181.6 tons of incendiary bombs and 1,477.7 tons of high explosive bombs, targeting the rail yards at the centre of the city. The inner city of Dresden was largely destroyed. The high explosive bombs damaged buildings and exposed their wooden structures, while the incendiaries ignited them, denying their use by retreating German troops and refugees. Widely quoted Nazi propaganda reports claimed 200,000 deaths, but the German Dresden Historians' Commission, made up of 13 prominent German historians, in an official 2010 report published after five years of research concluded that casualties numbered between 22,500 and 25,000. The Allies described the operation as the legitimate bombing of a military and industrial target. Several researchers have argued that the February attacks were disproportionate. As a result of inadequate Nazi air raid measures for refugees, mostly women and children died. American author Kurt Vonnegut's novel Slaughterhouse Five is loosely based on his first-hand experience of the raid as a POW. In remembrance of the victims, the anniversaries of the bombing of Dresden are marked with peace demonstrations, devotions and marches.
