21st/22nd August 1917
This Zeppelin raid, the first since the loss of L.48 on the night of 16/17 June, is somewhat shrouded in mystery. Eight Zeppelins set out from Germany but British records only report one, L.41 commanded by Hauptman Kuno Manger, coming inland. At the time the British defences were still coming to terms with the great heights of up to 20,000ft attainable by this latest class of Zeppelin.
L.41 crossed the East Yorkshire coast at Tunstall at 12.03am and nine minutes later passed a couple of miles north of an army camp at Halsham, before dropping an incendiary near Elstronwick at 12.20am. Ten minutes later she appeared to hover between Ryehill and Paull, south-east of Hull, at which point the searchlight at Paull opened but was unable to locate L.41 for 18 minutes due to her great height. At 12.50am the AA guns at Paull opened fire, soon joined by the lights and guns at Marfleet and Chase Hill Farm. Manger steered L.41 towards Paull as soon as the light there found him, dropping seven HE bombs as he approached, but as the fire increased he veered away to the north-east towards Hedon, which he bombed at 1.00am. Of five bombs, one fell in a field about 400 yards south of St. Augustine’s Church and the rest around Baxtergate where one man was injured. They wrecked a Primitive Methodist chapel, blew in the doors and windows of a Roman Catholic chapel and 11 dwellings, and seriously damaged a YMCA hut on the Burstwick Road.
Manger continued on a northward course, still keeping to the east of Hull, dropping two HE and 12 incendiary bombs about a mile east of Preston, followed by another HE bomb that fell in a wheat field about half a mile on. He then turned southwards and at 1.10am the Marfleet searchlight illuminated L.41 again before she dropped an HE bomb at Thorngumbald, without causing damage, as the guns at Marfleet and Paull opened fire. It appears Manger then took L.41 across the Humber but, engaged by more lights and guns, he turned back over the river and made his way to the coast, going out to sea at 1.40am north of Withernsea.
The RFC sent up 19 aircraft from Nos. 33 and 76 squadrons but nine of them were too late to be of any use. Those that were in the air in time, the best with a maximum ceiling of around 13,000ft, were unable to reach the heights the new class of Zeppelin could achieve if threatened. One pilot pursued L.41 out to sea for twenty miles without being able to gain the height needed to make a successful attack.
Confusion exists over the other Zeppelins that approached Britain that night. It appears two, L.35 and L.51, turned back early and two others, L.42 and L.45, claimed to have bombed shipping off Spurn Head, although this does not show in British records. Three others claim to have made attacks: L.44 on Lincoln, L.46 on Louth and L.47 on Grimsby. British records show no bombs falling in these places, however there were reports, dismissed at the time, of Zeppelins near Pontefract and the sound of exploding bombs were reported from Doncaster. It is possible that the relevant authorities failed to discover bombs dropped in remote areas and from the great height Zeppelins were flying at the crews could have little hope of pinpointing where they were.
