Operation Bellerophon was a Sentinel operation conducted by Kilo Team in Chimera-occupied Poland on February 13th, 1951. However, Bellerophon ultimately ended in failure which left only one member of Kilo, Joseph Capelli, as the sole survivor. On March 9th, Sentinel Team Bravo discovered and recovered Capelli in a conversion center in Warsaw.[1]
