John Keegan – internationally renowned military historian, bestselling author, and lecturer – has died at the age of 78. He was the author of over 20 books on the nature of warfare, including  military strategy, the experience of the individual at war, and the challenges of leadership. Frank C. Mahncke, an  author and operational research analyst, described him as being “among the most prominent and widely read military historians of the late twentieth century,” while fellow British historian deemed him “”at once the most readable and the most original of living historians.”

The Telegraph has written a wonderful tribute to his life, character, and long and illustrious career (excerpt below):

“Whatever the subject before him, Keegan wrote with close knowledge of the military arts and a personal acquaintance with many senior serving officers who had been his pupils; above all, he demonstrated a deep awareness of the human aspects of warfare, which was cruel, confusing and frightening, if occasionally glorious. It was always with surprise that new acquaintances discovered that Keegan was no battle-hardened veteran. He was a gentle civilian who was deeply imbued with his Roman Catholic faith and had been crippled with tuberculosis since childhood. While an unabashed supporter of the British alliance with the United States, he described himself as “95 per cent pacifist” and looked forward – though with increasing doubts in recent years — to a world which had abandoned war.”
