text_A: Over the course of his reign, higher taxes to pay for successful military campaigns were tolerated by the commoners and supported by the nobility, and John's own conflicts with the Pope led most of the barons to support him even more than in the past. However, in 1215, some of the most important barons rebelled against him. He met their leaders along with their French and Scot allies at Runnymede, near London on 15 June 1215 to seal the Great Charter ("Magna Carta" in Latin), which imposed legal limits on the king's personal powers. But as soon as hostilities ceased, John received approval from the Pope to break his word because he had made it under duress. This provoked the First Barons' War and a French invasion by Prince Louis of France invited by a majority of the English barons to replace John as king in London in May 1216. John travelled around the country to oppose the rebel forces, directing, among other operations, a two-month siege of the rebel-held Rochester Castle.
text_B: Does it sound like long military campaigns, even if they were essentially stalemates or failed conquests, were a chance for personal glory for the Barons and other nobility, regardless of how the rest of the population may have felt?
YES.
