So secret was Operation Bodenplatte that the Germans own ground forces were not notified of the large formations of German fighters that would be flying overhead. This resulted in at least one casualty for the JG11 as they were assaulted by friendly fire on their way to Asch. Credit must be given to the German pilots for not breaking radio silence to call off the ground fire. On the return trip several more JG11 and many other German fighters fell to friendly fire before the German guns could be called off.
As the JG11 approached Asch, 8 P47's of the 390th were just forming up over Asch to head out over the Ardennes in search of German armor. As the 390th finished forming up they spotted flak bursts over the Ophoven field. At this same moment Lt Col. John Meyer was just beginning to roll down the runway. He also saw the flak bursts and radioed the tower to inquire; the tower had nothing to report. Heading for Ophoven to investigate, the 390th was surprised to see a large formation of FW190's and Me109's approaching Asch from the northeast at 1500 ft
The 8 P47's of the 390th jettisoned their bombs and external tanks and attacked, causing confusion among the German attackers and breaking up the formation. This turned out to be a key blow to the JG11, without which the mustangs of the 487th may not have so easily taken to the air. The 390th claimed 7 enemy aircraft in this attack taking a loss of only one.

The battle over Asch went on for 30 minutes. 11 pilots of the 487th claimed 23 victories while sustaining no losses, and just three aircraft damaged in the air. I will leave the adventures of each pilot to be told by them through their personal combat logs and memoirs.
The 390th and 487th defended the airbase at Asch so well that only one Mustang was damaged on the ground and no casualties were reported. The actions of the 487th in taking off under fire and performing so well at such a disadvantage earned the unit the only Distinguished Unit Citation given to a fighter squadron in the Northwestern European theater of operation.
The total estimated losses of the JG11 range from 24 to 40. Given the credited victories of the 487th (23), 390th (7), 391st (2), and ground gunners (7) along with at least one aircraft destroyed by friendly flak in route, the number of 40 seems to hold up. However, there was undoubtedly some double counting of victories claimed and some victories that were not confirmed. But more Important then the numbers was the loss of experienced Luftwaffe leaders and pilots. None of JG11's flight leaders returned from this mission
