The following is a list of the casualties count in battles or offensives in world history.
Figures display numbers for all types of casualties when available (killed, wounded, missing, and sick) but may only include number killed due to a lack of total data on the event.
Tactical or strategic strikes, however, may form part of larger engagements which are themselves battles, small campaigns or offensives.
This list, sorted by year, includes sieges as well as modern battles fought primarily in urban areas.
The durations of some operations, like the Battle of Moscow, are disputed; so casualty numbers may differ for that reason alone.
