In 1768 Kościuszko's mother died, leaving her two daughters married, the eldest, spendthrift, and most beloved son out on his own, and Tadeusz still a cadet. With his mother's death Kościuszko's financial troubles began. For the greater part of his life he never knew what it was to have a sufficiency of means. His brother held the estate and apparently the control of the family money, that was no considerable sum and had in latter years diminished. Public affairs, moreover, were now assuming an aspect that threatened the very existence of Kościuszko's country. Catherine II's minister, Repnin, with Russian armies at his back, ruled the land. The Poles who stood forward in a last despairing attempt to deliver their country were removed by Russian troops to exile and Siberia. Then in 1768 rose under the Pułaski father and sons that gallant movement to save a nation's honour that is known as the Confederation of Bar. For four years the confederates fought in guerilla warfare all over Poland, in forest, marsh, hamlet, against the forces of Russia which held every town and fortress in the country. These things were the last that Kościuszko saw of the old Republic of Poland. In the company of his friend Orłowski, who had been one of four cadets to receive the King's stipend, he departed from his country in 1769 or 1770 with the intention of pursuing his studies abroad. Five years passed before Kościuszko saw his native land again. Very little is known to us of that stage of his history. It is certain that he studied in the school of engineering and artillery in Mézières and conceivably in the Ecole Militaire of Paris. He took private lessons in architecture from Perronet, and followed up his strong taste for drawing and painting. Sketches from his hand still remain, guarded as treasures in Polish national museums. French fortifications engaged his close attention, and by the time he left France he had acquired the skill in military engineering that saved a campaign in the New World and that defended Warsaw in the Old. It is said that Kościuszko prolonged his absence abroad rather than return to see the enslavement of his country without being able to raise a hand in her defence. For in 1772 Russia, Austria, and Prussia signed an agreement to partition Poland between them, which, after a desperate resistance on the part of the Polish Diet, was carried out in 1775. Austria secured Galicia, Prussia a part of Great Poland and, with the exception of Thorn and Danzig, what has since been known as "Prussian" Poland, while to Russia fell the whole of Lithuania.
