Passage: On 25 June 1656, Charles X Gustav signed an alliance with Brandenburg: the Treaty of Marienburg granted Greater Poland to Frederick William in return for military aid. While the Brandenburgian elector was free of Swedish vassalage in Greater Poland, he remained a Swedish vassal for the Duchy of Prussia. Brandenburgian garrisons then replaced the Swedish ones in Greater Poland, who went to reinforce Charles X Gustav's army. On 29 June however, Warsaw was stormed by John II Casimir, who had drawn up to Charles X Gustav with a force of 28,500 regulars and a noble levy of 18,000 to 20,000. Thereupon, Brandenburg actively participated in the war on the Swedish side, prompting John II Casimir Vasa to state that while his Tartars already had the Swedes for breakfast, he would now take Frederick William into custody, where neither sun nor moon would shine. Already in May 1656, Alexis of Russia had declared war on Sweden, taking advantage of Charles being bound in Poland, and Livonia, Estonia and Ingria secured only by a Livonian army of 2,200 infantry and 400 dragoons, Magnus de la Gardie's 7,000 men in Prussia, and 6,933 men dispersed in garrisons along the Eastern Baltic coast. Alexis invaded Livonia in July with 35,000 men and took Dunaburg.

Passage: The violence and terror of Pontiac's War convinced many western Pennsylvanians that their government was not doing enough to protect them. This discontent was manifested most seriously in an uprising led by a vigilante group that came to be known as the Paxton Boys, so-called because they were primarily from the area around the Pennsylvania village of Paxton . The Paxtonians turned their anger towards Native Americansmany of them Christianswho lived peacefully in small enclaves in the midst of white Pennsylvania settlements. Prompted by rumors that a Native war party had been seen at the Native village of Conestoga, on December 14, 1763, a group of more than 50 Paxton Boys marched on the village and murdered the six Susquehannocks they found there. Pennsylvania officials placed the remaining 16 Susquehannocks in protective custody in Lancaster, but on December 27 the Paxton Boys broke into the jail and slaughtered most of them. Governor John Penn issued bounties for the arrest of the murderers, but no one came forward to identify them. The Paxton Boys then set their sights on other Native Americans living within eastern Pennsylvania, many of whom fled to Philadelphia for protection. Several hundred Paxtonians marched on Philadelphia in January 1764, where the presence of British troops and Philadelphia militia prevented them from committing more violence. Benjamin Franklin, who had helped organize the local militia, negotiated with the Paxton leaders and brought an end to the immediate crisis. Franklin published a scathing indictment of the Paxton Boys. "If an Indian injures me," he asked, "does it follow that I may revenge that Injury on all Indians?" One leader of the Paxton Boys was Lazarus Stewart who would be killed in the Wyoming Massacre of 1778.
