Oglethorpe was a first-rate soldier. He defeated a superior Spanish force from Florida, and successfully resisted attacks from the Indians. Also, he was a man whose ethical sense was in advance of his period. He did not permit slavery in Georgia, and it was not adopted there until he went back to England. In planning Savannah he was assisted by a Charleston engineer named Bull, for whom the chief street of Savannah is named. The place is laid out very simply; it has rectangular blocks and wide roads, with small parks, or squares, at regular intervals. There are some two dozen of these small parks, aside from one or two larger parks, a parade ground, and numerous boulevards with double roadways and parked centers, and the abundance of semi-tropical foliage and of airy spaces, in Savannah, gives the city its most distinctive and charming quality--the quality which differentiates it from all other American cities. Originally these parks were used as market-places and rallying points in case of Indian attack; now they serve the equally utilitarian purposes of this age, having become charming public gardens and playgrounds. One of them--not the most important one--is named Oglethorpe Square; but the monument to Oglethorpe is placed elsewhere. Madison Square, Savannah, is relatively about as important as Madison Square, New York, and though smaller than the latter, is much prettier. It contains a monument to Sergeant Jasper, the Revolutionary hero who, when the flag was shot down from Fort Moultrie, off Charleston, by the British, flung it to the breeze again, under fire. Jasper was later killed with the flag in his arms, in the French-American attempt to take Savannah from the British. Monterey Square has a statue of Count Pulaski, who also fell at the siege of Savannah. Another Revolutionary hero remembered with a monument is General Nathanael Greene who, though born in Rhode Island, moved after the war to Georgia where, in recognition of his services, he was given an estate not far from Savannah. "Mad" Anthony Wayne, a Pennsylvanian by birth, also accepted an estate in Georgia and resided there after the Revolution.
