Sanad ka dib, dagaalku wuxuu qaatay qaab ka duwan qaabkii hore, Brooke waxay aaminsantahay inaysan u baahneyn in ay garab istaagto Churchill. Sidaa darteed wuxuu rajaynayay in uu qabsado hogaanka
Dagaalkii Allied ee galbeedka yurub, booska Brooke wuxuu aaminsanaa in Churchill uu u balan qaaday seddex jeer. Intii lagu guda jiray Shirkii ugu horreeyay ee Quebec bishii Ogosto 1943, waxaa la go'aamiyay in taliska uu aado General George Marshall. (In kasta oo ay dhacday in shaqada Marshall ee Madaxa Shaqaalaha Ciidanka Mareykanka ay aad muhiim ugu ahayd inuu ka tago Washington DC iyo Dwight D. Eisenhower ayaa loo magacaabay meeshii.) Brooke aad ayuu uga niyad jabay, labadaba in laga gudbo iyo qaabka go'aanka uu u gudbiyay Churchill, oo sida laga soo xigtay Brooke "u maareeyay arrinta sidii inay ahayd mid aan muhiimad weyn lahayn".
