“who was to blame for britain’s failure to win a quick victory over the american rebels: general howe, general burgoyne, or the ministers in london? explain your answer.”

General Howe was most responsible: Rather than destroying the rebels, Howe encouraged Congress to surrender, buying the rebels further time during the winter of 1777 to improve their forces.
Howe's slow and misguided attack against Philadelphia contributed to General Burgoyne's loss at Saratoga, New York.
