The supineness of Howe robbed the British of all the benefits that might have resulted from the capture of Philadelphia. Attempts were made to raise regiments of loyalists, but so little support did the scheme receive that it was only partially successful. The "Pennsylvania Loyalists", of which William Allen, Jr., was colonel, and the "Queen's Rangers", commanded by Lieutenant-Colonel Simcoe, were the most efficient of these corps. No attempt was made to drive Washington's half-starved forces from their camp, although their condition was perfectly well known to Howe through the deserters that flocked to the city. The military movements of Howe while in Philadelphia were confined to foraging expeditions and attacks on isolated posts that could be surprised and broken up with little danger of loss. While these were successful, they gave to the war a predatory character that reflected little credit on British arms, and intensified the bitterness entertained for all representatives of royal authority. The British government, dissatisfied with the results of Howe's campaigns, decided early in 1778 upon his recall. Sir Henry Clinton, his successor, arrived in Philadelphia the 8th of May, and on the 18th an entertainment was given by the officers of the army in honor of the retiring commander. The fête was styled the "Mischianza", and consisted of a regatta, a mock tournament, and a ball. But "Knights of the Burning Mountain" and of the "Blended Rose", with squires and ladies decked with spangles and ribbons, could not disguise the fact that the royal army had failed in accomplishing the task assigned to it, and the chagrin of its veterans was deepened by the frivolous scenes which marked the retirement of Sir William Howe.
