During the flight, the bomber was attacked by an enemy fighter but, although damage was sustained, making the bomber difficult to control, Flight Lieutenant Mandeno continued to the target and bombed it.

Five nights later, when returning from an attack on Cologne, his aircraft was hit by gunfire from an enemy aircraft. The elevator and the tailplane were damaged, one of the port engines was put outof action and a petrol tank was pierced. Despite this, Flight Lieutenant Mandeno flew the bomber . to base.
