兵火 is a more literary, less common word for fires caused by military action, closely matching the literal sense of 戦火.
戦火 and 戦禍 are pronounced identically but 戦火 literally means the 'flames/fires of war' (i.e. fighting or combat itself), while 戦禍 means the damage and suffering that result from war.
戦火 means the destruction or 'flames' of war itself, not a place, so it should not be confused with 戦地, which denotes the actual war-zone location.
Compound of 戦 (war, battle) and 火 (fire). The literal meaning 'wartime fire' extended figuratively to the broader destruction and horrors of war.
