From the review:
Although his forceful leadership qualities are unquestionable, Henry is changed by his experience on the French battlefields. Mr. Amendt slowly peels off the steel-clad surface of the king to reveal the layers of doubt and anxiety that assail him in the bleak dawn before the big battle. The play’s most moving scene is the king’s incognito stroll among his soldiers, when he confronts both their weary pragmatism and their natural distaste for the grim business of war. Henry’s cool, almost haughty demeanor softens and shrinks to human dimensions in the company of these men, as the burden of leadership begins to weigh on his soul.
