The Prince of Homburg, disobeys orders and leads a cavalry charge in battle against the Swedes, which leads to victory. He is court martialled however for disobeying orders and sentenced to death. His love who is now to be betrothed to the King of Sweden, following his execution appeals to the Elector, her uncle, on his behalf, as do his comrades in battle. He must also contend with his own desire to live and conflicting sense of honour.
I love this!
