Battle of Flamborough Head<span> began. </span>Serapis<span> engaged </span>Bonhomme Richard<span>, and soon afterwards, </span>Alliance<span> fired, from a considerable distance, at </span>Countess<span>. Quickly recognizing that he could not win a battle of big guns, and with the wind dying, Jones made every effort to lock </span>Richard<span> and </span>Serapis<span> together (his famous, albeit possibly </span>apocryphal<span>, quotation "I have not yet begun to fight!" was uttered in reply to a demand to surrender in this phase of the battle)</span>
