is a war hero Because of his bravery the Bulgarian army wins a crucial battle In reality he won the battle by accident The audience finds it funny that Raina thinks of him as a great hero Bluntschli reveals that Sergius cavalry charge worked because the enemy had the wrong bullets and could not shoot He says Sergius cavalry charge was like Throwing peas at a window Sergius acts like a dramatic storybook knight like Don Quixote Hence Sergius heroism is a farce Shaw uses this farce to make fun of the foolish ideals about war heroism and bravery Foolish Love The foolish love between Raina and Sergius is also a farce Sergius and Raina pretend to have a perfect romance but they are both attracted to other people Sergius flirts with Louka behind Raina s back Raina secretly admires Bluntschli This leads to confusion and humorous situations Coat Episode Another farcical moment is when Petkoff cannot find his coat Catherine and Raina try to hide the truth that they gave Bluntschli the coat The situation becomes more ridiculous when Bluntschli returns with it at the worst possible moment In short these farcical elements make the play entertaining and engaging The characters act in silly ways but through humor Shaw makes serious points about war and love
