After the collision happened, the captain gave several orders to his officers/crew to assess the damage or to tour the ship, then waking the off-duty officers, and the captain consulting with Andrews etc. But what happened in the meantime on the bridge? Were Moody and Murdoch still on the bridge and awaiting updates from the captain/Boxhall about the severity of the situation, did the 1st and 6th Officer maybe talk to each other about what just happened and how bad it could be? Like what did Murdoch and Moody do as the ship started to slow down/stop and everyone else touring the ship? I wonder what exchanges happened between the remaining officers on the bridge.
A very good question on the lines that I have often thought about myself. Since both those Officers as well as Captain Smith died that night, we will never know for certain but a few guesses could be made.
Since both Murdoch and Moody were on duty at the time of the accident, I believe they would have been obliged to remain on watch on the bridge until such time as the Captain ordered them to do otherwise. Since the engines were briefly restarted and the
Titanic made a slight headway, I assume that it would have been Murdoch who vocalized the Captain's orders to that effect. When Smith went on his inspection tour, Murdoch and Moody remained on the bridge AFAIK and it would have been natural for them to discuss among themselves what had just happened and the seriousness of the outcome. They also appear to have started taking some preliminary action.
AB Buley recalled that Murdoch ordered him to get more of his colleagues together and start uncovering the lifeboats very early. I believe Murdoch would have required Captain Smith's authorization for that action and so it follows that Smith might have been playing safe even before he found out the worst from Andrews. Moody ordered Olliver to get the list of crew lifeboat assignments (OASOG).
And who else was on the bridge with them and what do we know happened there during the timespan when the damage was inspected?
QM Hichens, the helmsman, remained at his station within the enclosed wheelhouse for the time being.
QM Olliver was the first "outsider" to arrive on the bridge after the accident and saw Murdoch at the lever to activate the water-tight doors. The Captain arrived next and after discussing what had happened with Murdoch, sent Olliver away to fetch the ship's carpenter. Boxhall arrived on the bridge after Captain Smith and after Olliver had left and was ordered to go forward below to inspect for signs of damage and flooding. His first inspection appeared to show nothing significant but they soon learned from the carpenter and one of the mail clerks that the mail room was flooding rapidly.
Thomas Andrews probably arrived on the bridge within a few minutes after the collision. He was seen by Eleanor Cassebeer, who also left her cabin almost immediately after the impact, reassuring the few passengers who were milling about.
It is a bit difficult to guess at what time Bruce Ismay first arrived on the bridge but it appears to have been about 10 minutes after the collision. IF, the Captain really then told the Chairman that he thought that the damage to the ship could be serious, I wonder how the former knew that. Boxhall had found no damage after his first hurried inspection and Smith had not received any report yet from Andrews. So, my guess is that Ismay arrived after the carpenter and/or the mail clerk came to the bridge to report flooding. It is also possible that he had heard from Wilde, who would have come directly to the bridge after he left Hemming and Foley at the forecastle.
