While archival research can be slim pickings, I suspect that this may not be such a problem for my Great War panics project, given that on my recent trip the UK I found some really good examples without even trying. The following is an excerpt from a letter dated 7 June 1915, sent to the navalist and journalist Arnold White by a member of the public (the first item in the list is a -- false, as far as I can tell -- claim that the same man had been captain of both HMS Bulwark and HMS Princess Irene and had left 15 minutes before each was sunk by internal explosions, and was court-martialled and shot):
Second, the last German Zeppelin raid [presumably 4 June 1915] has been very serious in loss of life at Tilbury, Gravesend, Greenwich Hospital, Enfield and elsewhere. The [objective] was Woolwich where Von Donop is [still] in charge. Engineers who meet him daily are astounded at the Government keeping him there!
Third, the 'guide' to the last raid is, as I have previously referred to, a motor cyclist with a side seat and a woman. This I have from a man who saw it flashing an upward light at the last raid with a Zeppelin following. I have seen the couple pass my house at Castlenau several times -- they go at great speed.
Fourth, I hear, again on good authority and from an Engineer who has frequently to meet von Donop, that the next Zeppelin raid in force will be made, (as they now know their ground) on Woolwich and that the German Navy will come out to meet our Navy, and the opportunity will be made for the German [transports] to slip out and attempt a landing at Southend. [Personally] I believe the S.E.Kent Coast will also be a base for their operations -- Ramsgate in particular -- they want waking up there -- Especially the Chief Constable -- its [sic] still a hotbed of spies.1
So Major-General Stanley Von Donop, Master-General of the Ordnance, is a suspicious character, apparently even more so since Woolwich Arsenal was the objective of the last Zeppelin raid, which caused serious loss of life. He may be connected with the couple in the motorcycle and sidecar who were seen guiding the Zeppelin. He is also apparently somehow involved in the next Zeppelin raid, also on Woolwich, which will be coordinated with a sortie by the German fleet and a landing by the German army at Southend in Essex. Also, spies or something in Kent. Of course, the spineless authorities are doing nothing about it. (White, at least, was paying attention: in 1917 he published The Hidden Hand detailing German infiltration and subversion of Britain.)
Just about none of this was true: if Von Donop, grandson of a German nobleman but son of a British admiral, was a German agent, he was never found out; spies did not go out at night to guide Zeppelins to their targets; nobody was killed in the air raid of 4 June 1915; the next Zeppelin attack wasn't on Woolwich but on Hull, and there was no German fleet sortie then, let alone a landing in Essex. In fact, this is an excellent example of the intersection and interaction of the three types of scares I am looking at: invasion, spies, air raids. These didn't exist in isolation, but could complement and reinforce each other, in a sum of the British people's fears.
