Hitler's secretary, [[Traudl Junge]], recalled that Hitler repeatedly spoke in late 1943 or early 1944 of a possible bomber attack on the ''Wolfsschanze'' by the Western [[Allies of World War II|Allies]]. She quoted Hitler as saying, "They know ''exactly'' where we are, and sometime they're going to destroy everything here with carefully aimed bombs. I expect them to attack any day."<ref>{{cite book|author=Junge, Traudl|title=Until the Final Hour|publisher=Weidenfeld & Nicolson|year=2003|page=116}}</ref>

According to Speer, between 28 July 1941 and 20 March 1942, Hitler left Rastenburg only four times for a total of 57 days.  Afterwards, Hitler spent the next three months in [[Obersalzberg]] before returning to Rastenburg for the next nine months.<ref name="Speer 2">{{cite book |last1=Speer|first1=Albert|title=Inside the Third Reich|date=1995|publisher=Weidenfeld & Nicolson|location=London |isbn=9781842127353 |page=401}}</ref>

Hitler's entourage returned to the ''Wolfsschanze'' from an extended summer stay at the [[Berghof (residence)|Berghof]] in July 1944. The previous small bunkers had been replaced by the [[Organisation Todt]] with "heavy, colossal structures" of reinforced concrete as defense against the feared air attack.<ref>Junge, Traudl. ''Until the Final Hour''. Weidenfeld & Nicolson, 2003, p. 126.</ref> According to Armaments Minister [[Albert Speer]], "some 36,000,000 marks were spent for bunkers in Rastenburg [Wolf's Lair]."<ref name = "Speer">Speer, A: ''Inside the Third Reich'', p. 217</ref>

Hitler's bunker had become the largest, "a positive fortress" containing "a maze of passages, rooms and halls." Junge wrote, "We had air-raid warnings every day" in the period between the [[20 July plot|20 July assassination attempt]] and Hitler's final departure from the ''Wolfsschanze'' in November 1944, "but there was never more than a single aircraft circling over the forest, and no bombs were dropped. All the same, Hitler took the danger very seriously, and thought all these reconnaissance flights were in preparation for the big raid he was expecting."<ref>Junge, Traudl. ''Until the Final Hour''. Weidenfeld & Nicolson, 2003, p. 145.</ref>

No air attack ever came. It has never been revealed whether the Western Allies knew of the ''Wolfsschanze''{{'}}s location and importance.  The Soviet Union was unaware of both the location and the scale of the complex until the site was uncovered by its forces during their advance towards Berlin in early 1945.<ref>[[Antony Beevor|Beevor, Antony]] (1999) ''Stalingrad: The Fateful Siege: 1942–1943''.
