Shakespeare's Henry V is of course one of greatest plays ever written but beyond literature, Shakespeare's mastery of character means there is also much to learn from it about leadership. Henry is a king and a soldier, taking his men to war at Agincourt, outnumbered 20 to one by the French and expecting with much of his company to die. On the morning of the battle, Henry takes the temperature of the situation. I found myself quite amazed how Shakespeare's devices and King Henry's words and thoughts have resonance in the wisdom of one of the modern era's greatest soldiers, former US 4 star General Colin Powell. Here I draw out a few things of significance.
