I've actually read a similar situation where II/JG11 (one of the more successful RVG Gruppen) consisting of 20 (+/- 2-3... a Gruppe would usually consist of 40+ aircraft but JG11 took very heavy casualties throughout the war) 109's jumped a group of 40-60 Mustangs (going off of memory I don't remember well) from the sun and destroyed many for not many losses.
I just remembered I've already copied this story from 'I Flew for the Fuehrer' and posted it on the boards. Without further adieu,
'
3rd March, 1944The Americans attack Hamburg. Specht cannot fly, and I am in temporary command of the Gruppe. Our original forty aircraft have now been reduced to eighteen. These I take into the air.
Over Hamburg I prepare to attack a small formation of Fortresses. My eighteen crates are 5,000 feet above them. Just as I am about to dive, I observe, about 3,000 feet below and to the left, a pack of some sixty Mustangs. They cannot see us, for we happen to be directly between them and the dazzling sun.
This is a magnificent opportunity!
I throttle back to allow the enemy pack to get a little way ahead of us. Wenneckers draws alongside, waving and clasping his hands in delight. For once we are in a position to teach them a real lesson, but I must be careful not to dive too soon. They have not spotted us yet. After them!
In a practically vertical dive we hurtle into the midst of the Yanks, and almost simultaneously we open fire. We take them completely by surprise. In great spirals the Mustangs attempt to get away. Several of them are in flames before they can reach the clouds. One literally disintegrates under fire from my guns.
Yells of triumph echo over our radio.
In the evening I receive the report from Division that the wreckage of no fewer than twelve Mustangs had been found in map reference sectors Caesar Anton four and seven.
There is only one drop of sorrow to tinge the general rejoicing. Methuselah has not returned. Several of the pilots saw a Messerschmitt 109 without wings going down. What has become of Methuselah?'
Methuselah had bailed safely and survived, albeit injured.
