Most terrible was the awakening from this dream of safety, when, on the morning of the 17th of August, the division under the command of Admiral Cockburn--the most dreaded and abhorred of all--was seen to enter the mouth of the Patuxent in full sail for Benedict. Nearly all the able-bodied men were absent with the army at the time when the combined military and naval forces tinder Admiral Cockburn and General Ross landed at that place. None remained to guard the homes but aged men, women, infants and negroes. A universal panic seized the neighborhood and nothing occurred to the defenseless people but instant flight. Females and children were hastily put into carriages, the most valuable items of plate or money hastily packed up, negroes mustered and the whole caravan put upon a hurried march for Prince George's, Montgomery or other upper counties of the State. With very few exceptions, the farms and plantations were evacuated and left to the mercy of the invaders. At sunrise all was noise, bustle and confusion at Luckenough. The lawn was filled with baggage wagons, horses, mules, cows, oxen, sheep, swine, baskets of poultry, barrels of provisions, boxes of property, and men and maid servants hurrying wildly about among them, carrying trunks and parcels, loading carts, tackling harness, marshaling cattle and making other preparations for a rapid retreat toward Commodore Waugh's patrimonial estate in Montgomery County. Edith was placed upon her pony and attended by her old maid Jenny and her old groom Oliver. Commodore and Mrs. Waugh entered the family carriage, which they pretty well filled up. Mrs. Waugh's woman sat upon the box behind and the Commodore's man drove the coach. And the whole family party set forward on their journey. They went in advance of the caravan so as not to be hindered and inconvenienced by its slow and cumbrous movements. A ride of three miles through the old forest brought them to the open, hilly country. Here the road forked. And here the family were to separate. It had been arranged that as Edith was too delicate to bear the forced march of days' and nights' continuance before they could reach Montgomery, she should proceed to Hay Hill, a plantation near the line of Charles County, owned by Colonel Fairlie, whose young daughter Fanny, recently made a bride, had been the schoolmate of Edith. Here, at the fork, the party halted to take leave. Commodore Waugh called his niece to ride up to the carriage window and gave her many messages for Colonel Fairlie, for Fanny and for Fanny's young bridegroom, and many charges to be careful and prudent, and not to ride out unattended, etc.
