Two separate events. Strategic bombing raids by "1000 planes" would refer to B-29 raids, not horizontal bombing done by Navy Avengers in squadron strength, as show in the photo above. In fact, there never was a "1000" bomber raid on a single Japanese target. The most was 828 B-29s, escorted by 186 P-51s flown on August 13 / 14 and targeting several cities throughout the course of the day and night.
