generals, but not soldiers;" and Baron Steuben wrote to a Prussian officer a little later: "You say to your soldier, 'Do this,' and he doeth it; but I am obliged to say to mine, 'This is the reason why you ought to do that,' and then he does it." The British officers were often incapable, but they had a military training, and were accustomed to require and to observe discipline. The American officers came in most cases from civil life, had no social superiority over their men, and were so unruly that John Adams wrote in 1777: "They quarrel like cats and dogs. They worry one another like mastiffs, scrambling for rank and pay like apes for nuts." [Sidenote: Commanders.] The success of the Revolution was, nevertheless, due to the personal qualities of these officers and their troops, when directed by able commanders. In the early stages of the war the British generals were slow, timid, unready, and inefficient. Putnam, Wayne, Greene, and other American generals were natural soldiers; and in Washington we have the one man who never made a serious blunder, who was never frightened, who never despaired, and whose unflinching confidence was the rallying point of the military forces of the nation. [Sidenote: Plans of campaign.] The theatre of the war was more favorable to the British than to the Americans. There were no fortresses, and the coast was everywhere open to the landing of expeditions. The simplest military principle demanded the isolation of New England, the source and centre of the Revolution, from the rest of the colonies. From 1776 the British occupied the town of New York, and they held Canada. A combined military operation from both South and North would give them the valley of the Hudson. The failure of Burgoyne's expedition in 1777 prevented the success of this manoeuvre. The war was then transferred to the Southern colonies, with the intention to roll up the line of defence, as the French line had been rolled up in 1758; but whenever the British attempted to penetrate far into the country from the sea-coast, they were eventually worsted and driven back. 36.
