First launched on 8 August 1917, Zeppelin LZ 100 (L 53) took part in 19 reconnaissance missions; 4 attacks on England, dropping 11,930 kg (26,300 lb) of bombs.

Flight Sub-Lieutenant Stuart D Culley was born in Nebraska in 1895 of a Canadian mother and an English father.

[1] On 11 August Redoubt, towing H5, was sailing as part of the Harwich Force on a sweep of Heligoland Bight when Zeppelin LZ 100 was spotted.

[2][3] Ascended to a height of 19,000 feet, at which altitude he attacked an enemy airship, and brought it down in flames completely destroyed.

This was a most difficult undertaking involving great personal risk, and the highest praise is due to Lieutenant Culley for the gallantry and skill he displayed.
