It occurs to me that no matter the evidence against or in support of Captain Lord's position some have decided to condemn the man. While I definitly see why one would do that, I think it would be wise to look at the over all picture governing his decision making.
Whether he ignored the rockets or thought that they where something different from what they where isn't the issue. The Safe a prudent navigation of his vessel and his responsibility to the men aboard it where his sole responsibility and should be the issue being discussed as apart of this over all discussion. The fate of those on Titanic does not fall upon his (Captain Lords) shoulders, his shipmate Captain Smith is to be held responsible for this.
In my professional opinion and (and with 90 years of hindsight and my career being in the age of radio) Lord made a mistake by not waking his wireless operator but the biggest mistake was not making a formal decision and having it and the situation logged.
Some have argued that the fact he did not come to Titanic's aid was a decision in and of itself. As another Master Mariner I can not blame him for staying put, his responsibility was to his ship and his men, that was it, the problems that faced Titanic where not of his creating and not his to fix. If he felt that the ice around him was not dangerous then he wouldn't have stopped for the night, because none of us where there to see what he saw none of us can say with any amount of certainty the conditions in which Lord found himself. Because he was a Captain (a position that is not easily achieved) one must IMO give him the benefit of the doubt. I can however call him a poopy pants for not having the presence of mind to have his decision and the situation logged.
I have said in several threads that my officers only need to be told what I think is important, and that my orders in and of themselves give information about a decision that I have made to a competent officer. Hindsight tells me that this was a out of the ordinary situation one that I would hope would have caught my attention.
I grew up in the era of the Coast Guard and the era of Lawyers, and era where passenger ship captains can get sued for bad food and loose there jobs based decisions that are made for the safety of the ship and not the schedule. So, every decision that is even remotely questionable is logged.
Stanely Lord is guilty for not logging and informing his officers of a decision, especially after they had awakened him more then once about the situation. He is not guilty of manslaughter and he is not some evil being that slept peacefully knowing that 1500 people 10 miles away where about to die. Before folks make comments about Captain Lords decision to sleep after his ship stopped for the night, one might try being a skipper. Hindsight helps us see what happened, it does not help the men who where in the situation.
