“But the invasion of France was made possible by the drugs. No drugs, no invasion. When Hitler heard about the plan to invade through Ardennes, he loved it [the allies were massed in northern Belgium]. But the high command said: it’s not possible, at night we have to rest, and they [the allies] will retreat and we will be stuck in the mountains. But then the stimulant decree was released, and that enabled them to stay awake for three days and three nights.”
