While Matsuoka was in Berlin, preparations for ‘Marita’ were already furiously taking shape. Within little over a week they were ready. ‘Operation Marita’ was now set to begin at 5.20a.m. on Sunday morning,
The time seemed to drag. Goebbels drank tea with Hitler and, as a diversion, they talked about matters other than the war. Hitler turned to one of his favourite topics: making Linz into a cultural capital greater than Vienna. Goebbels said he would help as far as possible, in the first instance by setting up film studios there.138 Another hour passed. Then 5.20a.m. came. The attack had started. Hitler felt he could now go to bed.139
Shortly afterwards, Goebbels read out on the radio the proclamation Hitler had dictated.140 By then, hundreds of Luftwaffe bombers were turning Belgrade into a heap of smoking ruins. Hitler justified the action to the German people as retaliation against a ‘Serbian criminal clique’ in Belgrade which, in the pay of the British Secret Service, was attempting, as in 1914, to spread the war in the Balkans. The German troops would end their action once the ‘Belgrade conspirators’ had been overthrown and the last British soldiers had been forced out of the region.141 What could, of course, not be revealed was that the invasion of Yugoslavia would, in at least one important respect, be a trial-run for ‘Barbarossa’. Hitler had spoken privately about the campaign being ‘merciless
With the campaign in its early stages, Hitler left Berlin on the evening of 10 April,
Hitler remained in his secluded, heavily guarded field headquarters for a fortnight. He was visited there by King Boris of Bulgaria, Admiral Horthy, the regent of Hungary, and Count Ciano — vultures gathering at the corpse of Yugoslavia.146 His fifty-second birthday on 20 April was bizarrely celebrated with a concert in front of the Special Train, after Göring had eulogized the Führer’s genius as a military commander, and Hitler had shaken the hand of each of his armed forces’ chiefs.147 While there Hitler heard the news of the capitulation of both Yugoslavia and Greece.148
After overcoming some early tenacious resistance, the dual campaign against Yugoslavia and Greece had made unexpectedly rapid progress.149 In fact, German operational planning had grossly overestimated the weak enemy forces. Of the twenty-nine German divisions engaged in the Balkans, only ten were in action for more than six days.150 On 10 April Zagreb was reached, and an independent Croatian State proclaimed, resting on the slaughterous anti-Serb Ustasha Movement. Two days later Belgrade was reached. On 17 April the Yugoslav army surrendered unconditionally. Around 344,000 men entered German captivity. Losses on the victors’ side were a mere 151 dead with 392 wounded and fifteen missing.151
