The Chroniclers suggest that at Agincourt Henry V either grabbed his sword and shouted “follow me lads” or he gave an inspiring speech. As a writer, Shakespeare naturally chose the latter.
This is one of the most inspiring leadership speeches there is. It is worth analysing how Henry ensures all his team are committed, how he emphasises the team rather that the heroic leader, and how he uses a vision of the future to influence the present.
Worth 10 minutes to watch and think.
