A History of Warfare is a book by military historian John Keegan, which was published in 1993 by Random House.
It discusses early warfare, the proliferation of Bronze Age warfare and then Iron Age warfare. It also talks about the conquests of the "horse peoples", first under the Assyrians, then the Achaemenids, Parthians and Sassanids; then in the 7th century the Arabs conquer a lot of territory, followed by the Mongols under Genghis Khan and finally the last of the horse peoples under a Mongol named Tamerlane, who unleashes massive carnage and destruction.
The rise of medieval Europe causes the raising of money for castles, with infantry being paid to dig under castles for their destruction. Western Europe perfects castles that are impregnable. At the same time, cavalry is gradually eliminated from the battlefield; matchlocks, flintlocks and eventually Smith & Wesson revolvers become dominant.
In World War I, mustard gas, grenades, artillery and guns kill a massive number of soldiers that are buried in muddy graveyards on the Western Front. In World War II, millions die on the Eastern Front because of Adolf Hitler's theories of living space
