That is the excellent new book by Richard Overy, a leading historian of the Second World War. From this book I learned that:
1. The first bombing attack on Freiburg im Breisgau killed 57 people, and it was conducted by German bombers, who thought the city was the French town of Dijon.
2. In early 1945, the main hostility of the German population was directed toward the Italians, from switching sides in 1943, and not toward the bombing Allied nations.
3. More tons of bombs were dropped on Rome than on all British cities combined.
4. Per square mile, the most bombed place on earth was…Malta.
