CPO Jackman was lost together with all hands when HMS URGE was mined shortly after leaving Malta on 27 April 1942, although they were not declared officially dead until 6 May when the submarine was overdue and declared lost.

Captain Simpson of the 10th Flotilla wrote: “In Urge’s fine ship’s company one rating stands out with a record that must be for all time exceptional. Chief Petty Officer C. J. Jackman … had been in action during this war well over 40 times against all types of enemy ships”.

Charley Jackman was awarded the DSM and Bar and mentioned in despatches twice. He was the husband of Elsie Rosalie Jackman of Brockenhurst, Hampshire. His medals were donated by his family to the RN Submarine Museum and are on display on the upper level of the John Fieldhouse Building. His family also donated a kneeler to the chapel.

Charley Jackman’s cousin, James Jackman  (q.v.), was lost in HMS OLYMPUS, in the same minefield, just a few days later.
