Book excerpt: During the American Revolutionary War, Great Britain's Royal Navy faced foes that included, in addition to American forces, the navies of France, Spain and the Netherlands. In this operational history of a period that proved to be a turning point for one of the world's great naval powers, David Syrett presents a saga of battles, blockades, great fleet cruises and, above all, failures and lost opportunities. He explains that the British government severely underestimated the Americans' maritime strength and how that error led to devastating consequences. The seemingly invincible navy failed to muster even one decisive victory during the extensive naval conflict.
