Adam Mickiewicz 
Pan Tadeusz. The Last Foray in Lithuania [PDF ebook] 
A Tale of the Polish Nobility in the Years 1811 and 1812 in Twelve Books

Arguably the most authoritative English translation of Polands great national poem.Sometimes called the last epos in world literature, Pan Tadeusz(first published in Paris in 1834) is a classic tale of romance, mystery, war, and patriotism set in the turbulent Napoleonic era. The old Polish-Lithuanian Commonwealth lies dismembered and erased from the political map of Europe by the great powers of Russia, Prussia, and Austria. A brief ray of hope rekindles national aspirations when Napoleon Bonaparte establishes the Grand Duchy of Warsaw by the terms of the Treaty of Tilsit (1807) and sets the stage for his invasion of Russia.
