Q: Question: Which general had a more successful career, Gates or Burgoyne? Passage:In the fall of 1777 forces of the British Army successfully captured Philadelphia, the seat of the Second Continental Congress, which was forced to relocate to York, Pennsylvania. The series of military setbacks (principally the losses at Brandywine in September and Germantown in October) caused many in the Continental Army and Congress to question George Washington's leadership of the war effort. In contrast, the northern army of General Horatio Gates had won a signal victory over John Burgoyne's forces, compelling Burgoyne to surrender his entire army after the Battles of Saratoga. Gates controversially claimed credit for the victory. Some historians feel that this was more due to the actions of Benedict Arnold, who, in the first battle on September 19, effectively and almost independently defended his forces against British assaults. It was also alleged that Gates had failed to provide Arnold with adequate reinforcements which would have turned the battle into an outright American victory, although there is not universal agreement on this matter. Gates was politically well connected to Congress. Some congressmen such as Richard Henry Lee, John Adams, and Samuel Adams wanted tighter Congressional control of the war effort and supported Gates. Although John Adams did not specifically call for Washington to be replaced, he worried that Washington was being made into a military idol, and was fearful of the effects of this upon republicanism.
