Lyons was promoted to mate in October 1853 and transferred to the paddle frigate HMS Firebrand, which was engaged in the blockade of the Danube Delta, which was being held by the Russians at the start of the Crimean War.[4] Lyons was promoted to lieutenant on 26 June 1854.[2][3]
Lyons’s Rampage at the Danube
During the blockade of the mouth of the Danube, Captain Parker, Lyons's commanding officer, decided to attack the guardhouses and signal stations higher up the River, for these were responsible for the supply and communication of the Russian enemy. On 8 July, Captain Parker proceeded up the Danube, the banks of which were lined by Cossacks, who opened fire. When he reached the first Russian fort, defended by a stockade and a battery, Captain Parker was shot and killed by a Cossack.[3][2]
When Parker was killed, Lyons took control of the British boats and proceeded to destroy not only the first Russian signal station, but the next four signal stations up the River, causing the Russians to flee. For this, he was mentioned in dispatches.[3][2]
Lyons then became commander of HMS Firebrand for the bombardment of Sevastopol in October 1854, which was led by his uncle, Admiral Edmund Lyons, 1st Baron Lyons. When the British flagship, HMS Albion, was set on fire by the Russians, Lyons attached it, whilst burning, to his own ship and towed it to safety.[2]
Lyons married Louisa Jane Penrice (bapt. 1853), daughter and heir of Thomas Penrice, at Pennard Church in Kilvrough on 3 September 1879: they had two sons and two daughters.[5] Their residence was Kilvrough Manor in Glamorgan, where he died on 9 February 1908.[5]
