This was then and still is today, one of the main points in Ranger school or really any other infantry or small unit tactics. EVERYONE learns to be in charge and complete the objective. During Ranger school, Cadre will come up to the lowest private in a squad during an evolution/patrol and tell them, "Your squad leader has just been killed/wounded, you are now in charge, complete the objective".
Excellent book.
Recommended to ALL to know the sacrifice of not only that day, but ALL of WWII.
Unofficially recognized in the Airborne community as LGOPS (little groups of paratroopers).
The misplacement of the drops and the scattering of the Airborne (plus the dummies/Ruperts with explosives) made the Germans think they were either dealing with a much larger assault force or a feint depending on what they ran up against.
The British actually switched to night raids because their appalling losses conducting daylight raids prior to us getting into the European theater. They tried to convince our leadership to do the same and attack at night, but you are correct, we insisted on the accuracy of the Norden bomb (which really was proven later to not be that accurate) and to do the same during daylight. Our crew losses during 1943 and early 1944 were so high that we almost relented and switched to nighttime bombing only. Only US airplane production, losses to Germany's fuel oil (losses in Russia) and the development of long range fighter escorts, P47s and P51s, with the 51 not being suitable until the British experimented with it and put their Rolls Royce engine, the same as the Spitfire's, led to great success.
