The Henrietta sloop, of Ballylongford, was boarded last Friday morning, in the mouth of the Adare river, on her passage home from Limerick, by six men, armed and with their faces painted, who ordered all the passengers up on deck, and rifled the persons of every one of them, carrying off a good booty. While engaged in this daring outrage, the ruffians presented fire arms at the heads of their victims, threatening instant death in the event of resistance. They also went below and seaarched the cargo, consisting of groceries, woollens and mercery, and plundered a bale of silk handkerchiefs, muslins, laces, and shawls.
On the same night a sail-boat belonging to Knock, county Clare, was also plundered by a party of ruffians, who boarded her in the Shannon.
