What happened July 1754AD

The full Virginia Regiment joined Washington at Fort Necessity the following month with news that he had been promoted to command of the regiment and to colonel upon the death of the regimental commander. The regiment was reinforced by an independent company of 100 South Carolinians led by Captain James Mackay, whose royal commission outranked that of Washington, and a conflict of command ensued. On July 3, a French force attacked with 900 men, and the ensuing battle (Battle of Fort Necessity) ended in Washington's surrender. In the aftermath, Colonel James Innes took command of intercolonial forces, the Virginia Regiment was divided, and Washington was offered a captaincy which he refused, with resignation of his commission.
