initial landing and follow-up. (The Overlord invasion of Normandy, by comparison, deployed 12 divisions in the initial landings.) In the initial stage, the First Army would have invaded at Kujūkuri Beach, on the Bōsō Peninsula, while the Eighth Army invaded at Hiratsuka, on Sagami Bay; these armies would have comprised 25 divisions between them. Later, a follow-up force of up to 20 additional U.S. divisions and up to 5 or more British Commonwealth divisions would have landed as reinforcements. The Allied forces would then have driven north and inland, encircling Tokyo and pressing on toward Nagano. Redeployment Olympic was to be mounted with resources already present in the Pacific, including the British Pacific Fleet, a Commonwealth formation that included at least eighteen aircraft carriers (providing 25% of the Allied air power) and four battleships. Tiger Force, a joint Commonwealth long-range heavy bomber unit, was to be transferred from RAF, RAAF, RCAF and RNZAF units and personnel serving with RAF Bomber Command in Europe. In 1944, early planning proposed a force of 500–1,000 aircraft, including units dedicated to aerial refueling. Planning was later scaled back to 22 squadrons and, by the time the war ended, to 10 squadrons: between 120 and 150 Avro Lancasters/Lincolns, operating out of airbases on Okinawa. Tiger Force was to have included the elite 617 Squadron, also known as "The Dambusters", which carried out specialist bombing operations. Initially, US planners also did not plan to use any non-US Allied ground forces in Operation Downfall. Had reinforcements been needed at an early stage of Olympic, they would have been diverted from US forces being assembled for Coronet—for which there was to be a massive redeployment of units from the US Army's Southwest Pacific, China-Burma-India and European commands, among others. These would have included spearheads of the war in Europe such as the US First Army (15 divisions) and the Eighth Air Force. These redeployments would have been complicated by the simultaneous demobilization and replacement of highly experienced, time-served personnel, which would have drastically reduced the combat effectiveness of many units. The Australian government had asked at an early stage for the inclusion of an Australian Army infantry division in the first wave (Olympic). This was rejected by U.S. commanders and even the initial plans for Coronet, according to U.S. historian John Ray Skates, did not envisage that units from Commonwealth or other Allied armies would be landed on
