Have we under-estimated the number of volunteers?
In June 2011, the National Archives’ release of a list of 4000 names of those the British Security Services belived to be on their way to fight in Spain, created a bit of a stir. Tom Buchanan wrote a piece for The Guardian and I was interviewed by Jon Snow on Channel 4 news.
It was a good story. However, the over-zealous spooks included reporters, war-tourists, visitors and holiday makers on the list, so historians agree that there’s no reason to discount the previous estimates just yet.
