Through the spring of 1792 Kościuszko was preparing the division of the army under his command for the war with Russia. His were still the heart-burnings that he was to experience whenever he was at the head of men, those of a commander who had neither sufficient soldiers, ammunition, nor provisions. On the 21st of May the King delivered a stirring speech to the Diet. "You behold deeds," he said, alluding to the Confederation of Targowica, "that aim at the destruction of the authority and existence of the present Diet and of the restoration of our entire independence. You behold the open support of those compatriots who are committing violence against the welfare and will of our country. You behold, therefore, the indispensable necessity that we should adopt as best we can every measure to defend and save our country. Whatever, honourable Estates, you resolve I will not only accede to, but I hereby declare that I will take my place in person wheresoever my presence shall be called for." Probably those of his audience who knew the King best took his words at their true value. On May 22nd the Russian army crossed the frontier. Poland appealed to the terms of her treaty with Prussia, and requested the Prussian state to come to her assistance. Prussia threw off the mask and disavowed her treaty obligations; and the Poles were left to their own resources. Their numbers equalled, according to Kościuszko's computation, one single column of the Russian army. An empty treasury, an empty arsenal, were behind them; they were pitted against seasoned soldiers, trained in successful war; but the fire of patriotism ran high through their ranks. Many of the nobles, following the old traditions of Polish history, raised regiments in their own provinces, armed them at their own cost, and in person led them to the field. The commander-in-chief was young Józef Poniatowski, the nephew of the King. He was to become one of the most popular of Poland's heroes, as the brilliant leader of a Polish army during the Napoleonic wars; but at this moment he was a youth of twenty-eight, whose military knowledge was wholly negligible, and who owed his high position to his family connections. The only Polish general who had practical experience of war was Kościuszko; and with him, for all Poniatowski's devoted service of his country, rests the chief fame of the Ukraine campaign.
