John Marshall (Royal Navy officer, born 1785)

For his services in the North Sea Marshall was knighted by Russia and Sweden, made a Companion of the Order of the Bath, and promoted to post-captain.

[3][4] In December 1805, still in the East Indies, Marshall followed Caulfield into the 74-gun ship of the line HMS Russell and at the same time was promoted to master's mate.

In October 1806 the Commander-in-Chief, Rear-Admiral Sir Edward Pellew, had Marshall transferred to his flagship, the 74-gun ship of the line HMS Culloden, as an acting lieutenant.

[3] Aboukir subsequently joined the Baltic squadron of Rear-Admiral Thomas Byam Martin that was tasked with supporting Russia against Napoleon's invasion of 1812.

The senior surviving officer Lieutenant Henry Ducie Chads reported that despite being a passenger Marshall had provided support and advice throughout the battle and was slightly injured.

[3][6] Marshall was given command of a squadron of gun boats, with which he sailed up the Elbe to Glückstadt, where he was to support the advance of a Swedish force towards the town.

The British enhanced their batteries with more cannon and launched another attack in cooperation with their Swedish allies from land and sea on 1 January, but this was also repulsed.

[9] Marshall received the thanks of Captain Arthur Farquhar, the over-all commander of the naval operations, for his services in the drawn out assault.

[3][10] On 9 January, having found much difficulty in navigating his ship through the ice surrounding the town, Marshall brought his force into the harbour where he captured a Danish flotilla consisting of a brig and seven gunboats that had been holed up there.

[3] On 31 August 1842 Vice-Admiral Sir Edward Durnford King appointed Marshall to lead a board of inquiry into the loss of the convict ship Waterloo.

He completed his report on 10 September, criticising Waterloo's captain for choosing to anchor in Table Bay in bad weather and for doing little to assist in the rescue of the convicts onboard.

[14] For his services at the Cape of Good Hope he was thanked by the Committee at Lloyd's in April 1845, having returned home to pay off Isis at the start of the year.

[15] Some time after his promotion, Marshall was badly injured in a fall from his gig and was taken to the house of Major-General Sir Charles Smith at Pendyffryn near Conwy.
