The moments that decided it
DAY 186
Supply crisis for Czechia
This moment mattered because momentum shifted durably toward Poland: ammunition stocks are running low and opposing air interdiction of supply routes.
Think it would go differently?
This run assumed no allies, winter, full mobilization for the attacker and partial for the defender, and no nuclear weapons. Change any of that and watch it play out day by day on the map.
After 362 simulated days the conflict between Poland and Czechia ended with: Ceasefire, front frozen (prolonged stalemate). Aggregate personnel losses within the model: 15,903 (Poland) and 2,112 (Czechia). The model identified 1 turning point. This page reports one seeded run of a model on public, aggregate data.
