One more thing from the Cardigan biography, though it doesn’t pertain to Cardigan himself:
Artillery bombardment became something of a sport [during the siege of Sebastopol]. A Russian officer under a flag of truce entered the British lines and proposed a contest between the best British 68-pounder, ‘Jenny’, and the champion Russian gun... General Airey accepted the challenge and, at noon, all other firing ceased along the line of battle. The sailors of the Naval Brigade and their Russian opponents climbed on to their respective parapets and saluted one another. Then the English gun, being the senior, was allowed to fire first. After a number of alternate shots, the seventh shell from the English gun knocked the Russian gun on its side, at which the English sailors cheered loudly, and the Russian survivors removed their hats to acknowledge their defeat. Then general war was resumed along the front.
