The moment in context
Guadalcanal was the first sustained Allied ground offensive of the Pacific war, and its lessons shaped everything that followed. Six months of grinding fighting on land, at sea, and in the air exhausted both sides, while tropical disease inflicted enormous losses of its own. Japan finally evacuated the island in February 1943. The result proved two things at once, that the Japanese perimeter could be pushed back, and that assaulting every defended island in turn would be far too costly to sustain across the whole ocean.
From Pacific island-hopping campaign, chapter 11 of The War Room — WW2, 1936–1945 (NOV 1943).

- What it changed — The perimeter becomes a prison. Watch the red line on the map shrink from snapshot to snapshot. Each lost anchor (Gilberts → Marshalls → Marianas) exposes the next; bypassed…
