Analysis of information sources in references of the Wikipedia article "Charge of the Light Brigade" in English language version.
Martin Landfried retired as bandmaster for the 1st Sussex Artillery Volunteers at Shoreham Fort, West Sussex, UK. He left the army in 1865 [...] At the time of his death he was living in Portland Road Hove and his grave is Hove Cemetery. The recording was made and distributed by the Light Brigade Relief Fund. The aim was to benefit the remaining veterans and inform the public about the bad times some of them had fallen on. [...] Researched by Hilary Greenwood, Shoreham Fort historian. Landfried's name is misspelled as "Landfrey" at the beginning of the annotations to the recording; and the annotations refer to the instrument as a trumpet, but Landfried twice calls it a bugle.
Later Landfried became famous as the man who sounded the charge of the Light Brigade but it is not clear whether this was his responsibility or not. Taking part in the charge were 17 men listed as trumpeters on the muster rolls... including William Brittain who rode with Lord Cardigan in the Charge. [...] There is much argument about whether the 'charge' was actually sounded at all [...] William Brittain, it is agreed, sounded the 'walk, trot, gallop' and he may have sounded the 'charge.' It may be that one or more of the other trumpeters sounded the charge.
