Churchill is in fashion again. His wartime leadership made him one of the character studies in Supreme Command. He's been used as a model of executive leadership. He and Reagan have been the subjects of a joint study. The one limitation of all these studies is that they focus on his wartime leadership, often giving little background to his earlier political career. That's fine for most Americans - most of us probably conceive of Churchill as having emerged from the womb arguing for an increase in the air defence budget.
In fact, Churchill is a far more complex political character than we usually think of. He had ambitions back to early adulthood, and fueled by his spendthrift sop of a father's own failed bid for greatness. As Americans, who know about "never surrender" and Iron Curtains, and all that, it's easy to forget that before the Wilderness Years would have been neither Wilderness nor Years if he weren't already a major public figure. By the 30s, the British public already had an image of Churchill in their minds, shaped by his earlier career.
To get a feel for how Churchill's early public life shaped his later public life, you can either wade through Manchester's readable books, or you can pick up John Keegan's sketch, Winston Churchill, as part of the Penguin Lives series. Keegan covers all the major episodes - the River War, the Dardanelles, his pacing back and forth across the Parliamentary floor, and of course, his wartime Premiership. But there's much more to the man - even the public man - both before and, as importantly, after the war.
At first blush, Keegan might seem an odd choice for the job. He's known primarily for his military histories, and as mentioned, this biography has a wider scope than that. But Keegan has always understood war as a political venture more than a purely military one. In that sense, Churchill's earlier career really was preparation for his wartime and post-war leadership.
Churchill chose an odd route to public life - a military career that served mostly as a means to a journalistic one. Like the best bloggers, he could write about the Boer War and the River War because he had been there, been shot at (without result), and had the training to know what he was looking at. Michael Yon, eat your heart out. Unlike bloggers, though, the only outlet of the day was the newspaper, and he needed his mother's considerable influence to get published at first.
