The attack did not take place; and on the 6th of September the Prussians retired from Warsaw. During the whole course of the siege, with the exception of one post they had taken in its earliest stage, they had gained not one inch against the Poles defending their city with smaller numbers and inferior ammunition. The Russians retreated with the Prussians. They had remained almost immovable during the siege. Neither of these two collaborators in the destruction of Poland were on the best terms with each other, and Catherine II had no mind to share with Prussia the distinction, and still less the profits, of bringing Warsaw to its knees. Austria, although she was by way of being at war with Kościuszko, had held aloof from the siege, unwilling to commit herself, but determined on coming in for the spoils when the Rising should be crushed out.
Kościuszko then tasted one of the greatest triumphs of his life: the armies of the enemy were no more seen round the city he had saved.
"By your assiduity, your valour," the National Council wrote to him, "you have curbed the pride and power of that foe who, after pressing upon us so threateningly, has been forced to retreat with shame upon his covetous intentions. The Council knows only too well the magnitude of the labours which you brought to the defence of this city, and therefore cannot but make known to you that most lively gratitude and esteem with which all this city is penetrated. "[2]

Further, it expressed the wish that Kościuszko should show himself to a grateful people in some solemn function.
To this Kościuszko politely replied, declining to take any share in a public honour which it was against every dictate of his nature to accept.
"I have read with the greatest gratitude and emotion the flattering expressions of the Supreme National Council. I rejoice equally with every good citizen at the liberation of the city from the enemy armies. I ascribe this to nothing else but to Providence, to the valour of the Polish soldiers, to the zeal and courage of the citizens of Warsaw, to the diligence of the government. I place myself entirely at the disposition of the Supreme National Council: in what manner and when do you wish the celebration to take place? My occupations will not permit me the pleasure of being with you. I venture to trust that the God who has delivered the capital will deliver our country likewise. Then, as a citizen, not as a bearer of office, will I offer my thanks to God and share with every one the universal joy."[1]

He stayed in his camp and, in order to avoid an ovation, did not enter Warsaw. No public triumph was celebrated, but Masses of thanksgiving were sung in every church of the city.
