Operation Vivaldi began before the advance. It moved a sector, not the war
Between late May and mid-October 2026 Ukraine's 3rd Army Corps retook a string of villages north of Lyman. The advance was the last stage of a longer process — a sector stabilised, a command reorganised, an operation kept off the map, Russian supply and drones struck first. Its effects reached beyond the ground taken. The eastern front around it is still a war of attrition.
