I know that this is an old post, but during my research into a sailor on HMS Blenhein I came across this by the Pembroke Historical Society
During the latter months of 1861 repairs were carried out at Milford. These included the replacement of fittings and furniture demolished in the gale, while saloons and berths were rearranged and put in order.57 The principal repairs were new paddlewheels, rudder head and sailing gear. One of the principal contracts was awarded to James Gaddarn of Neyland that ‘spirited s hipbuilder’ 58 to build a large coffer-dam in order to facilitate repairs to the sternpost and rudder. This work required all the men in his employ.
On Sunday 16 February 1862 an attempt was made to berth the Great Eastern on the gridiron. The attempt ended in disaster. Assisted by three steam tugs, she rounded the Wear Point but during the operation the snapping of a hawser drew into the screw of the Great Eastern a boat containing men belonging to HMS Blenheim. Thirteen men threw themselves into the water, the remaining were ‘rapidly sucked into the maelstrom of waters formed by the screw revolution.’ 59 Two men were drowned, Thomas James of Milford and a boy named Kinston, a native of Ireland. To compound the horror, the Great Eastern struck HMS Blenheim carrying away her bow sprit, jib-boom and foreyard. The damage was estimated at £350.60 The 60-gun screw ship of 1,822 tons, guardship in the Haven and commanded by Lord Frederick Kerr had sustained considerable damage.
