A historical episode which, if it happened this year, would quite possibly win the Zbig Brzezinski Prize for Myopia. From page 342 of an interesting but overly-long book, Operation Kronstadt, by Harry Ferguson:
But before Paul [Dukes, MI6’s operative in Bolshevik Russia just after the revolution] could put his plan into operation, disaster struck. Yudenich’s thrust towards Petrograd had failed. The advance had been so successful because it had been led by six tanks driven by British soldiers who had volunteered for the mission. The Red forces had no answer to them and it seemed as though Petrograd must fall. But when they reached Gatchina, just 20 miles south-west of Petrograd, the British Soldiers woke in the morning and found that the tanks had been sabotaged. Someone had poured sand into the gearboxes and without the proper spares the tanks had been reduced to so much scrap metal. The tanks had been sabotaged by officers of the White army. They were angry about British support for the independence of the Baltic states and Finland which they felt should remain part of the Russian empire. And they resented the idea that their former capital was about to be liberated by the British. The incident neatly summed up every reason why White resistance to the Bolsheviks failed.
There’s just no helping some people.
