In May 1771, Pulaski advanced on Zamość, refusing to coordinate an operation with Dumouriez against Alexander Suvorov; without Pulaski's support, the Confederates were defeated at the Battle of Lanckorona. Pulaski's forces were victorious at the Battle of Majdany, and briefly besieged Zamość, but it was relieved by Suvorov. He retreated, suffering major losses, towards Częstochowa. On July 27, pressured by Franciszka z Krasińskich, he declared he would from then on strictly adhere to orders from the Confederacy that he had previously habitually disregarded. In October his responsibilities in the War Council were increased, and the same month he became involved with the plan to kidnap King Poniatowski. Pulaski was initially opposed to this plan but later supported it on the condition that the king would not be harmed. The attempt failed, weakening the international reputation of the Confederates, and when Pulaski's involvement with the attempted kidnapping became known, the Austrians expelled him from their territories. He spent the following winter and spring in Częstochowa, during which time several of his followers were defeated, captured or killed.
