  Wreck of a Steamer. - We regret to state that as the screw steamer Mail, plying between the ports of Drogheda, Dundalk, Newry, and Ardrossan, and is the property of Messrs Malcomson, went aground near the light house, as she entered this port on Sunday evening last[6 March 1859]. She was nearly three hours behind the time of high water, and by some means or other got in the sand. Before she could be relieved, a storm sprung up and dashed the waves over her doing her immense damage. The Captain and crew had previously got ashore. A tug and lighters are now engaged striving to tow her from the place on which she lies. Her cargo consisted of merchandise and some coal. We have heard that an insurance for £3000 was afficted on her.

  No hopes are entertained that the screw steamer Mail which went on a sandbank close to Dundalk harbour lighthouse, will be got off. Great dissatisfaction prevails amongst those who had goods on board, as the owners of the vessel are not disposed to compensate them; they alleging that the vessel was in the hands of a pilot of the port, and that, consequently, they are not responsible.

Dundalk Herald - Saturday 17 June 1893
  DUNDALK HARBOUR. On Thursday, Captain Rigden (contractor for the removal of wrecks) and his brother, Mr H. Rigden, had their plant and staff in readiness, and made preparations for blowing up the screw steamer " Mail," of Dublin, lost in Dundalk Bay about 35 years ago. At low water the boiler of this wreck stood high out of the water and at a distance seemed like a large floating buoy. Mr H. Rigden having been enveloped in a diver's suit, descended to the wreck and laid four charges of Tonite, the new explosive used for submarine explosions. The diver having been taken into a boat, all the boats drew off to a safe distance, and then shortly followed four distinct explosions, water, sand and mud being thrown up to a great height. The old boiler apparently remained intact, and again the boats approached that object, and again Mr Rigden made a descent into the water and attached the explosive to the old boiler. Again the boats drew off, and in a short time there was a loud explosion, and water, mud, gravel and fragments of iron were blown into the air to the height perhaps of 200 feet. When the agitation of the water subsided, not a vestige of the old boiler was visible, but the tide by this time had risen.
