Writing Exercises: Minimalism - The Defense of the Weak

Pirates, munitions running out, sailed in retreat against stout hearts.
The battle raged, whilst no victor can be adjudged
Heaved mightily, to the last drop of blood
Weaklings, yet determined to defend their land
The townsfolk, manned the fortress guns
Fought against panic and fear
The fortress slowly crumbles
Hearts foul intent
Pirate cannons!
Boom!
