I thought this might be interesting to those interested in Russian Weapons in the Crimean War:
I did not know about these 13" Russian Mortars called 'Whistling Dick' until I read one of Captain Edward Marsh of the 34th Regiment's letters posted up by Swordswoman on this forum, where he mentions being in the trenches at Savastopol in January 1855 and being at the receiving end of 'Whistling Dick' and 9 pounders. I found this photo of the offending weapon on line with the following description:
'Whistling Dick' was a large Russian mortar situated in the Malakoff (or Malakhov), one of the main defensive redoubts at Sevastopol. Lefevre took this photograph just after the French had successfully assaulted the position on 8 September 1855, an act that marked the effective end of the siege of the Russian port.
