Philadelphia, which was to be the seat of the approaching campaign,
to take soundings in the Delaware, and to fortify Billingsport.

The enemy having landed at Hith, he joined the army and acted as
major of brigade.

At the battle of the Brandywine, he remained on the field after
his brigade had been routed, had a horse shot under him, and
carried off a piece of ordnance.

On the report of General Washington to Congress, it was ordered
that a horse be presented to M. de Fleury "as a mark of the high
sense Congress entertained of his merits." (_Certified by General
Washington and General Sullivan_).

N.B. This honour has been paid only to General Arnold and M. de
Fleury.

At the battle of Germantown he acted as brigade-major of
dragoons, charged several times, and made several prisoners. The
horse which had been given to him by Congress was shot under him,
and he himself was wounded in the leg. (_Certified by General
Count Pulaski_).

Fort Mifflin, on Mud Island, the only defence of the Delaware,
was threatened by the British army and squadron. It was a post of

Merlin, blew up under fire from the fort. The commandant and the
garrison, numbering 600 men, were relieved three times, but M. de
Fleury refused to leave the fort. He was wounded October 15th,
and the fort was evacuated that same night. For this action he
was made a lieutenant-colonel, and a letter of thanks was
addressed to him by the President of Congress. (_Certified by
Congress, the General-in-chief, and M. de la Fayette_).

During the winter of 1778 he formed the project of crossing the
ice and setting fire to the English squadron. The Delaware not

received orders to join the Army of the North. (_Certified by
General Washington and Commodore Hasilwood_).

The Canadian expedition did not take place, and on his return M.
