Warba(r)ch's death was described in the 88th Fighter Wing casualty report as follows:
Undertaking a recon in force, Lt. Cmdr. Condon commanded a flight to investigate sensor anomalies near Cairo III. Ambushed by a full squadron of enemy fighter craft, her flight acquitted itself in exemplary manner, recording 23 confirmed kills and 5 probable kills. By springing this ambush prematurely, and then effectively neutralizing it, Lt. Condon's flight prevented the Tiger Claw from entering harm's way. Only Lt. Maxwell and Lt. Polanski survived this encounter, and regretably, Lt. Maxwell died the next day of wounds sustained in this action. In this action alone, Lt. Warbach qualified as an Ace, while Lt. Cmdr. Condon achieved Ace of Ace standing.
