While he remained in this situation, de Viller, a French commander, at the head of nine hundred men, being on his march to dislodge Washington, detached one Jamonville, an inferior officer, with a small party, and a formal summons to colonel Washington, requiring him to quit the fort, which he pretended was built on ground belonging to the French, or their allies. So little regard was paid to this intimation, that the English fell upon this party, and, as the French affirm, without the least provocation, either slew or took the whole detachment. De Viller, incensed at these unprovoked hostilities, marched up to the attack, which Washington for some time sustained under manifold disadvantages. At length, however, he surrendered the fort upon capitulation, for the performance of which he left two officers as hostages in the hands of the French; and in his retreat was terribly harassed by the Indians, who plundered his baggage, and massacred his people. This event was no sooner known in England, than the British ambassador at Paris received directions to complain of it to the French ministry, as an open violation of the peace; but this representation had no effect.
