“Lafayette avoided the factions jealous of Washington because he recognized that Washington was the Revolution and that should he be reduced in power or replaced, the whole cause would collapse. … Washington was a shrewd judge of character and never would have warmed to Lafayette if he had been only a superficial ingratiating romantic. Lafayette scrupulously looked after his men, spending his own money when Congress failed to provide them necessities. Nor was he backward in suggesting to Washington certain changes and innovations from French military practice.”
