One of the Parliaments which King Charles assembled at length brought articles of impeachment against Buckingham, and a long contest arose on this subject. An impeachment is a trial of a high officer of state for maladministration of his office. All sorts of charges were brought against Buckingham, most of which were true. The king considered their interfering to call one of his ministers to account as wholly intolerable. He sent them orders to dismiss that subject from their deliberations, and to proceed immediately with their work of laying taxes to raise money, or he would dissolve the Parliament as he had done before. He reminded them that the Parliaments were entirely "in his power for their calling, sitting, and dissolution, and as he found their fruits were for good or evil, so they were to continue, or not to be." If they would mend their errors and do their duty, henceforward he would forgive the past; otherwise they were to expect his irreconcilable hostility. This language irritated instead of alarming them. The Commons persisted in their plan of impeachment. The king arrested the men whom they appointed as managers of the impeachment, and imprisoned them. The Commons remonstrated, and insisted that Buckingham should be dismissed from the king's service. The king, instead of dismissing him, took measures to have him appointed, in addition to all his other offices, Chancellor of the University of Cambridge, a very exalted station. Parliament remonstrated. The king, in retaliation, dissolved the Parliament. Thus things went on from bad to worse, and from worse to worse again; the chief cause of the difficulties, in almost all cases, being traceable to Buckingham's reckless and arbitrary conduct. He was continually doing something in the pursuit of his own ends, by the rash and heedless exercise of the vast powers committed to him, to make extensive and irreparable mischief. At one time he ordered a part of the fleet over to the coast of France, to enter the French service, the sailors expecting that they were to be employed against the Spaniards. They found, however, that, instead of going against the Spaniards, they were to be sent to Rochelle. Rochelle was a town in France in possession of the Protestants, and the King of France wished to subdue them. The sailors sent a remonstrance to their commander, begging not to be forced to fight against their brother Protestants. This remonstrance was, in form, what is called a _Round Robin_.
