During the collision of the Titanic with the iceberg, Pitman was in his cabin. Upon arriving at the scene, he was given control of Lifeboat 5 by First Officer Murdock. Also in his boat was Bruce Isamy. After getting as many women as possible in the boat, he allowed a number of men to come as well. In the boat, there was about 40 people, and was one of the first boats lowered from the starboard side. The other boat lowered at around the same time was No. 7.

After the sinking, Pitman testified at both inquires, and remained at sea for 35 more years. Although, because of failing vision, he had to leave the bride crew and become a purser. He was a widower and retired to Pitcombe, England until his death.
