He decided to attack the railway marshalling yards at Cologne instead and while he was approaching this target his aircraft was suddenly shaken by a succession of violent explosions. The cockpit filled with black fumes and Cheshire lost control of the aircraft, which dived about 2,000 feet, with its fuselage on fire. Cheshire regained control, the fire was extinguished and the Whitley, with a gaping hole in its fuselage, was brought safely back to base after, being in the air for 8 1/2 hours.
Enemy operations were chiefly confined to London and South-East England, although single attacks were reported in other districts and larger formations bombed Portland and Southampton on the 15th September. Several aerodromes were attacked, but none suffered damage of any importance. The main objectives appear to have been railways, public services and industrial targets : details of damage are set out in the Home Security Section. Attacks were, however, largely indiscriminate, particularly at night.
