"It would be great to see Osprey books in more educational settings. The level of detail they provide in a slender book is phenomenal. They remain an excellent value for the money to anyone wanting to learn the details of history." --Greater Games Industry (Spring 2011) "Author Marcus Cowper looks at the life of Henry V from a young prince struggling against insurrection to his command experience and eventual triumph in Northern France. He gives in-depth analysis to Henry's private motivations and aspirations, including some of his controversial military decisions and how he was perceived by his contemporaries as a military leader." --www.mataka.org (October 2010)
