An official letter written by Maitland in June 1805, gives us a vivid glimpse of frigate service in the old days:—

Captain Maitland to Rear-Admiral Drury, Cork.

Loire, Muros Road, Spain,
June 4, 1805.

Sir,—Being informed that there was a French privateer of 26 guns fitting out at Muros, and nearly ready for sea, it struck me, from my recollection of the bay (having been in it formerly, when lieutenant of the Kingfisher), as being practicable either to bring her out or destroy her with the ship I have the honour to command. I accordingly prepared yesterday evening for engaging at anchor, and appointed Mr Yeo, with Lieutenants Mallock and Douglas, of the marines, and Mr Clinch, master's-mate, to head the boarders and marines, amounting, officers included, to 50 men (being all that could be spared from anchoring the ship and working the guns), in landing and storming the fort, though I then had no idea its strength was so great as it has proved. At nine this morning, on the sea-breeze setting in, I stood for the bay in the ship, the men previously prepared, being in the boats ready to shove off. On hauling close round the point of the road, a small battery of 2 guns opened a fire on the ship; a few shot were returned; but perceiving it would annoy us considerably, from its situation, I desired Mr Yeo to push on shore and spike the guns; reminding the men of its being the anniversary of their Sovereign's birth, and that, for his sake, as well as their own credit, their utmost exertions must be used. Though such an injunction was unnecessary, it had a great effect in animating and raising the spirits of the people. As the ship drew in, and more fully opened the bay, I perceived a very long corvette, of 26 ports, apparently nearly ready for sea, and a large brig of 20 ports, in a state of fitting; but neither of them firing, led me to conclude they had not their guns on board, and left no other object to occupy my attention but a heavy fort, which at this moment opened to our view, within less than a quarter of a mile, and began a wonderfully well-directed fire, almost every shot taking place in the hull. Perceiving that, by standing further on, more guns would be brought to bear upon us, without our being enabled to near the fort so much as I wished, I ordered the helm to be put down; and when, from the way she had, we had gained an advantageous position, anchored with a spring, and commenced firing. Although I have but little doubt that, before long, we should have silenced the fort, yet, from the specimen they gave us, and being completely embrasured, it must have cost us many lives, and caused great injury to the ship, had not Mr Yeo's gallantry and good conduct soon put an end to their fire.

I must now revert to him and the party under his command. Having landed under the small battery on the point, it was instantly abandoned; but hardly had he time to spike the guns, when, at the distance of a quarter of a mile, he perceived a regular fort, ditched, and with a gate, which the enemy (fortunately never suspecting our landing) had neglected to secure, open a fire upon the ship. Without waiting for orders he pushed forward, and was opposed at the inner gate by the Governor, with such troops as were in the town, and the crews of the French privateers. From the testimony of the prisoners as well as our own men, it appears that Mr Yeo was the first who entered the fort, with one blow laid the Governor dead at his feet, and broke his own sabre in two. The other officers were despatched by such officers and men of ours as were most advanced, and the narrowness of the gate would permit to push forward. The remainder instantly fled to the further end of the fort, and from the ship we could perceive many of them leap from the embrasures upon the rocks, a height of above 25 feet. Such as laid down their arms received quarter....

The instant the Union was displayed at the fort, I sent and took possession of the enemies' vessels in the Road, consisting of the Confiance, French ship privateer, pierced for 26 twelves and nines, none of which, however, were on board; the Bélier, French privateer brig, pierced for 20 eighteen-pounder carronades; and a Spanish merchant brig in ballast. I then hoisted a flag of truce, and sent to inform the inhabitants of the town, that if they would deliver up such stores of the ship as were on shore, there would be no further molestation. The proposal was thankfully agreed to. I did not, however, think it advisable to allow the people to remain long enough to embark the guns, there being a large body of troops in the vicinity. A great many small vessels are in the bay, and hauled up on the beach. None of them having cargoes of any value, I conceive it an act of inhumanity to deprive the poorer inhabitants of the means of gaining their livelihood, and shall not molest them. On inspecting the brig, as she had only the lower rigging overhead, and was not in a state of forwardness, I found it impracticable to bring her away, and therefore set fire to her: she is now burnt to the water's edge. I cannot conclude my letter without giving the portion of credit that is their due to the officers and men on board the ship. They conducted themselves with the greatest steadiness and coolness; and although under a heavy fire, pointed their guns with the utmost precision, there being hardly a shot that did not take effect.... It is but fair at the same time to state that, much to the credit of the ship's company, the Bishop and one of the principal inhabitants of the town came off to express their gratitude for the orderly behaviour of the people, there not being one instance of pillage; and to make offer of every refreshment the place affords.

I am now waiting for the land breeze to carry us out, having already recalled the officers and men from the fort, the guns being spiked and thrown over the parapet, the carriages rendered unserviceable, and the embrasures, with part of the fort, blown up.

I have the honour to be, &c.,

Fred. L. Maitland.

On June 27, 1805, the Common Council of the City of London voted him their thanks for his distinguished conduct in Muros Bay. The Committee of the Patriotic Fund at Lloyd's presented him with a sword, and on October 18 he received the freedom of the city of Cork in recognition of his exertions for the protection of Irish trade.
