A few years ago, an article on the locomotor costs of moving in armour was published which made many steel-clad heads meet desks. Most of those heads belong to people who would be happy to explain what was wrong with the article in person, but are not used to writing up what they know with academic phrasing and careful footnotes, while the authors did not seem inclined to seek out more experts in making and wearing armour and humbly ask what they were missing, so it looked like article and response would continue to exist in two different worlds. But then a French scholar published his own article and shot his own video on the topic. And while the video does not mention its nemesis, the film has the kind of elegant beauty of a volta which sends an iron-shod spear-butt into an unprotected face.

I don’t have the strength in me to do that much when something is wrong in the library, unless writing the article has some hope of leading to a career. So praise him with great praise!

Edit 2018-01-18: Another response, which focuses on the way in which the early sources on Agincourt present marching across a muddy field in armour as only one of the many problems which the French faced, see Kelly DeVries, “Technological Determinisms of Victory at the Battle of Agincourt,” British Journal for Military History, Volume 2, Issue 1 (2015) pp. 2-14 http://www.bjmh.org.uk/index.php/bjmh/article/view/67 DeVries says that Andy Deane, one of the test subjects, was not at all impressed with the conclusions which the experimenters drew from their discovery that running in armour is tiring.
