1 Sqn RNAS made the first attack on Germany on the airship sheds at Düsseldorf and Cologne. Four aeroplanes set off but a thick mist extending from the river Roer to some miles east of the Rhine meant that only Flight Lieutenant Charles Collet succeeded in finding his objective. He glided down at Düsseldorf from a height of 6,000 feet, the last 1,500 feet through the mist. One of his bombs fell short and the others seem to have hit the shed, but failed to explode. All four machines were back in Antwerp by one o’clock in the afternoon.
Also today, Lt GW Mapplebeck RFC was wounded by a German two-seater whilst attempting to attack a kite balloon in his BE2a. He is the first British pilot to be wounded by fire from another aircraft.
Wing Commander Samson RNAS also made an armoured car reconnaissance from Douai to Aniche. Between Douai and Valenciennes, he engaged German cavalry.
