The Settlers in Canada by Frederick Marryat

The French sixty-gun ship proved to be the Leonidas; she had been sent out with two large frigates on purpose to intercept the convoy, but she had parted with her consorts in a gale of wind. Her loss of men was very great; that on board of the Portsmouth was trifling. In a couple of hours the Portsmouth and her prize in tow were ready to proceed with the convoy, but they still remained hove to, to wait for the frigates which were in chase of the captured vessels. All of these were speedily come up with except the London Merchant, which sailed so remarkably well. At last, to the great joy of Alfred (who as soon as the bullet had been extracted and his arm dressed, had held his telescope fixed upon the chase), she hove to, and was taken possession of. Before night, the convoy were again collected together, and were steering for their destination. The next morning was clear, and the breeze moderate.

Mrs. Campbell, who, as well as all the rest, was very anxious about Alfred, requested Captain Wilson to run down to the Portsmouth, that they might ascertain if he was safe. Captain Wilson did as she requested, and writing in chalk "all well" in large letters upon the log-board, held it over the side as he passed close to the Portsmouth. Alfred was not on deck -- fever had compelled him to remain in his hammock -- but Captain Lumley made the same reply on the log-board of the Portsmouth, and Mr. and Mrs. Campbell were satisfied.
