This would not be a good book for anyone without a good understanding of the events of WWI. It was published in 1923, just after the war, for a British audience who survived what was the most important event in most of their lives. If you're looking for a good history of the lead up and early days of WWI, read The Guns of August.
That said, I've read a lot of WWI history, and I enjoyed this book. It's 10% the run up to and events of 1914 and 90% what Winston Churchill was doing in 1910-14 as the civilian leader of The Admiralty. Honestly, reading this book you might wonder if WWI was really a naval war given the scope and perspective of this tome.
As with any war, not everything goes well or according to plan. Churchill goes to great lengths to explain why the cock ups of the British navy at the start of WWI were not his fault. Viz., the loss of three cruisers to German ships in the Pacific and the bombardment of non-military British population centers from the North Sea when in both areas of operations the British enjoyed massive naval superiority.
Churchill goes out of his way to share that he had predicted the flow of the first 90 days of the war on the Western Front with some accuracy...3 or 4 years before war broke out. I chalk this up to Churchill writing a lot about everything. People who like to prognosticate, and I am one as was Churchill, are going to score some bull's-eyes.
Among Churchill's most interesting observations:
In response to critics who claimed "If France had only done X" or "If England had only done Y" there would not have been a war, he says that from the inside X, Y, and A and B and C and J are all connected. One could not have adjusted X or Y without everything else changing, therefore such Monday morning quarterbacking was rubbish.
It was clear to Churchill in 1910 or 11 that Germany wanted war, based on separate manufactured crises with Russia and France leading up to the War. I found his explanation of these events new (to me) and enlightening.
Churchill takes a lot of credit for Britain's naval modernization in the three years leading up to WWI. Any improvement in arms that wasn't his idea was the idea of someone he had put into place. Completely true?
Churchill was at the Belgian front for a week or so, leading naval platoons that had been thrown into the effort to slow the German's push to Antwerp. I didn't know that before. According to Churchill, Lord Kitchener wanted to make him an admiral so that Churchill could continue as a military, rather than civilian, leader. The Prime Minister wouldn't allow it.
Churchill heaps praise on those he finds worthy, especially those who perished in the War. He doesn't grind axes. Disagreements in the cabinet are not brought forth, only the majority's decision, whether or not Churchill personally agreed. There are a couple of naval errors in judgment in battle that could not be ignored. Churchill never writes with scorn in describing these lapses.
Britain didn't have enough rifles at the start of WWI for every man in the military to have his own. Yikes!
Terrific narrator/reader.
