enough to warrant attacking those manufacturing Messerschmitt Bf 109s. The production of Bf 109s (and almost half of all German fighters) was located in Regensburg and in Wiener Neustadt, Austria. To attack these in sufficient force, "Operation Juggler" was conceived, in which the fighter production plants in Wiener Neustadt were targeted for attack by B-24 Liberators of the Ninth Air Force based in Libya, and Regensburg by B-17s of the Eighth Air Force. The original mission date of August 7 could not be met because of bad weather, and the B-24s flew Operation Juggler on August 13 without participation by the Eighth Air Force, which was still hampered by unacceptable weather conditions. To successfully complete its portion of the attack, the Eighth Air Force decided to attack a target in central Germany as well as Regensburg to divide and confuse German air defenses. The 4th Bombardment Wing, using B-17s equipped with "Tokyo (fuel) tanks" for longer range, would attack the Messerschmitt Bf 109 plants in Regensburg and then fly on to bases in Bône, Berteaux and Telergma (French Algeria). The 1st Bombardment Wing, following it, would turn northeast and bomb the ball-bearing factories of Schweinfurt (where almost the entire production of bearings was centralized) and by doing so catch German fighter aircraft on the ground re-arming and refueling. Because of limited range thanks to (inexplicably) not employing drop tanks, escorting P-47 Thunderbolt fighters would be able to protect the bombers only as far as Eupen, Belgium, which was roughly an hour's flying time from both of the targets. Two supporting attacks were also made a part of the overall mission plan. The first, a diversionary attack, involved the bombing of three locations along the French and Dutch coast: the German airfields at Bryas-Sud and Marck by American B-26 Marauder and Royal Air Force Mitchell medium bombers, and the marshalling yards at Dunkirk by other Mitchells, all timed to coincide with the Regensburg strike. The second was a series of attacks on Luftwaffe fighter fields at Poix, Lille-Vendeville, and Woensdrecht by Hawker Typhoons of the RAF simultaneous with the diversionary attack, and Poix by two groups of B-26s in the afternoon as the Schweinfurt force was returning. Donald Miller states: "LeMay's force was expected to take the brunt of the German counteroffensive, allowing the Schweinfurt armada to proceed to the target with only light resistance. With LeMay escaping over the Alps,
