On account of the brilliant success of his majesty's arms, and his allies, in France, by the complete victory gained by the Duke of York at the head of the British, and also by the Austrians, on the 26th of April last, in which the French General Chapuey was made prisoner, with fifty-seven pieces of their cannon taken, and a great slaughter of their troops, with a very inconsiderable loss of the British troops and their allies, the Commander in Chief orders a _feu de joie_ on the occasion at six o'clock this evening; for which purpose all the troops will be under arms and assemble with the naval battalion at five o'clock, and are to be marched to a conspicuous situation, in view of the enemy, to give three rounds of running fire. The whole of our artillery, drawn up in front of the line, are to fire three rounds. Each round of artillery to precede a round of small arms: running fire beginning at the right of the line; and to conclude with three hearty cheers.--Brigadier General Symes, who commands the line, will be so good as to place and arrange the troops on this occasion, pointing out the ground they are to assemble upon. The whole navy will fire a _feu de joie_, and the troops under the command of Brigadier General Dundas at the camp at Berville, at the same time. The Commander in Chief desires that his long, spirited, and determined orders, given out when the army sailed from Barbadoes on the expedition to Martinico, dated the 22d of January, may be read to the troops, particularly to the seamen, many of whom have not served on shore. This the commanding officers of corps and naval battalions will be answerable to the Commander in Chief is done; and at the same time to assure their men, that however it may hurt his feelings, he will put the said orders in full force upon any and every offender in future; for without strict discipline and good order, no good service can possibly be effected: and he again calls upon every officer in the army to assist him in this necessary work. The troops to receive one day's fresh meat, and two days salt provision and rum, to-morrow morning at day-break. Returns to be sent to the commissary general this evening. AFTER ORDERS.
