This is something I've been wondering about for ages. In The Impact of Air Power on the British People and their Government, Alfred Gollin notes, but does not explain, a recurring theme: the idea that after a damaging air raid, angry mobs would string up government ministers (or other servants of the public) from lamp-posts for failing to protect them. And I mean literally string them up. It's not something I've come across much in my own sources, but it does seem that Gollin was onto something. Clearly it fits into the idea that bombing would cause civilians to panic, but the lamp-post references seem oddly specific. Presumably there was some inspiration for all this talk.
The first is from Flight, 1 February 1913 (link; the emphasis in each case is mine):
And if war should come suddenly, we most certainly shall not have command of the air -- but the lamp-posts of Whitehall may have unfamiliar ornaments. And well it might be under the circumstances.
The second is Alfred Stead in Review of Reviews, also published in February 1913 (very knock-out blow, I must say):
In the past the mistakes of Ministers have been retrieved and this country has muddled through; but with regard to a possible attack from the air there will be no possibility of muddling through, and the disorganised and panic-stricken survivors of the population of London will have the sole, although sorry, satisfaction, before passing under German domination, of hanging the guilty Ministers.
The next one refers to 1917, but was published in 1929. It's Major-General E. B. Ashmore's reflection (or lack thereof) upon learning that he was to take charge of the London Air Defence Area:
The fact that I was exchanging the comparative safety of the Front for the probability of being hanged in the streets of London did not worry me.
Finally, jumping forward a bit, these remarks were made by Lord Beaverbrook in 1964. He was talking about 1940, when he became Minister of Aircraft Production:
I was TERRIFIED. If I failed I knew it meant a lamp-post for me. I took a sleeping-draught every night.
What I can't understand is where this idea that Londoners were prone to summarily executing ministers came from. I can't claim an encyclopedic knowledge of British history, but I don't think there was any precedent for that: it just wasn't done. Maybe the idea was a foreign import? After all, the Parisian mob was the trendsetter for riotous urban behaviour after 1789 -- but they went after the nobility, not so much the politicians, didn't they? Anyway, the guillotine was the symbol of Jacobin terror, not the lamp-post. Perhaps American lynchings were the inspiration? That might fit the mode of execution better, but not the subject, unless I'm missing the extrajudicial dismissal (with extreme prejudice) of a few cabinet secretaries.
So what's going on here?
