Please give more details on Knapp attack in 1944 without fighter escort on Axis shipping convoy.
In 1944, Col. Robert D. Knapp led an attack—without fighter escort—on an Axis shipping convoy that had fighter protection & was awarded a Silver Star. I would like more information about this mission. My father, Harold W. Larson, was the navigator on this flight.
I see that you have quoted from the Wikipedia article on Robert Knapp. It puts the attack in 1944. The official Air Force website (see link below) disagrees and puts the attack in 1943. According to Knapp's Silver Star citation, the attack was carried out on March 31, 1943.
The reason why the attack was carried out without fighter escort was related to the weather. The fighter escort and six of the fourteen B-25 bombers became separated from Knapp and the other seven bombers. Knapp then led the eight bombers off in search of enemy shipping. They found a convoy, but the convoy had fighter escort where they did not. They attacked even so, destroyed some of the fighters, sank one ship and damaged another.
