Military Dead

Working allocation: 425,000 soldiers killed in combat, from wounds, or from disease. Each = 1,000 lives.

Roman Republic — 25,000 military dead
Gallic Tribes — 400,000 military dead

Civilian Dead

575,000 civilians killed — from violence, famine, disease, and displacement. Wars are not fought only by soldiers.

Civilian dead — 575,000

Milestones of Loss

25,000 dead

Roman military losses across the entire campaign are estimated at 20,000–30,000 killed — relatively light for a conquering army, reflecting Roman tactical superiority in open battle but significant losses in ambushes and sieges.

400,000 dead

Caesar claimed in his dispatches to have killed 1 million Gauls and enslaved another million. Modern historians estimate 500,000–1,000,000 total deaths over the eight-year campaign; the figures here use conservative scholarly estimates.

Figures are working historical estimates and vary across sources. Labels identify totals that are reported, disputed, or unknown; numerical allocations may be retained for comparison without implying exact knowledge. Each number represents human lives, not false precision.
