arrival. Receiving reports of powerful Soviet concentrations behind the Kursk area, Hitler further delayed the offensive to allow for more equipment to reach the front. With pessimism for Citadel increasing with each delay, in June, Alfred Jodl, the Chief of Staff at the OKW, instructed the armed forces propaganda office to portray the upcoming operation as a limited counteroffensive. Due to concerns of an Allied landing in the south of France or in Italy and delays in deliveries of the new tanks, Hitler postponed again, this time to 20 June. Zeitzler was profoundly concerned with the delays, but he still supported the offensive. On 17–18 June, following a discussion in which the OKW Operations Staff suggested abandoning the offensive, Hitler further postponed the operation until 3 July. Finally, on 1 July, Hitler announced 5 July as the launch date of the offensive. A three-month quiet period descended upon the Eastern Front as the Soviets prepared their defences and the Germans attempted to build up their forces. The Germans used this period for specialised training of their assault troops. All units underwent training and combat rehearsals. The Waffen-SS had built a full-scale duplicate Soviet strong point that was used to practice the techniques for neutralizing such positions. The panzer divisions received replacement men and equipment and attempted to get back up to strength. The German forces to be used in the offensive included 12 panzer divisions and 5 panzergrenadier divisions, four of which had tank strengths greater than their neighbouring panzer divisions. However, the force was markedly deficient in infantry divisions, which were essential to hold ground and to secure the flanks. By the time the Germans initiated the offensive, their force amounted to around 777,000 men, 2,451 tanks and assault guns (70 percent of the German armour on the Eastern Front) and 7,417 guns and mortars. Soviet plans and preparation In 1943 an offensive by the Soviet Central, Bryansk and Western Fronts against Army Group Centre was abandoned shortly after it began in early March, when the southern flank of the Central Front was threatened by Army Group South. Soviet intelligence received information about German troop concentrations spotted at Orel and Kharkov, as well as details of an intended German offensive in the Kursk sector through the Lucy spy ring in Switzerland. The Soviets verified the intelligence via their spy in Britain, John Cairncross, at the Government Code and Cypher
