||D.S.O. 19 February 1915(Capt Flight Cdr)
“ On the 25th December 1914, an air reconnaissance of the Heligoland Bight, including Cuxhaven, Heligoland and Wilhelmshaven was made by seven naval seaplanes, and the opportunity was taken at the same time of attacking with bombs, points of military importance. The reconnaissance involved combined operations with light cruisers and destroyers, and submarines watching inshore and ready to render aid if necessary.
The vessels detailed having arrived at the rendezvous before daylight, as soon the light was sufficient, the seaplanes were hoisted out (from HMS Engadin) and despatched. At the beginning of the flight the weather was clear, but on nearing land the seaplanes met with thick weather and were compelled to fly low, thus becoming exposed to a heavy fire at a short range. Several machines were hit, but all remained in the air for three hours and succeeded in obtaining valuable information regarding dispositions of the enemy's ships and defences. Bombs were dropped on military points.
Capt. Kilner's and two other machines regained their ship. Three others, short fuel, were compelled to descend and their pilots were saved by Submarine 'E1' although subjected to fire from an airship. The pilot of the remaining sea plane,having lost his bearings, was compelled to descend after 3 ½ hours flight, owing to engine trouble and was rescued by a Dutch trawler and returned safely to England."
