My reading may have reached 2000 pages on the subject (including several hundred original documents).
My target is a 4000 word essay.
Writing 40,000 words is easy; a Tweet is easy too - Blame Reich Chancellor Bethmann Hollweg, Kaiser Wilhelm II and Moltke.
A summary of 600 words, expanded to 2000 words is straightforward too. The problem is 4000 words - here the need and expectation to prove a point required considerable fine and considered editing of the mass of evidence.
There are over 23000 books on the First World War. I've read perhaps 40 of them and own 100. Do I know enough? Have I satisfied this itch once and for all?
