We were flying CAP over C3, we had a 5 mile box around the CV in a stack formation. After a while of this we incountered multiple cons to our high blind side. Our highest stack was at 20k and down, the allied planes were well above us and went strait for the CV. All F4U's and P-40's, don't know actual count but there were a lot of them. We tried to stand our ground as long as we could, but nevertheless succumb to enemy action. Sorry if we didn't hold our end of the duties but we were just overwhelmed.
