The account of the drowning of Turgesius is given with tantalising curtness in the "Book of Leinster": "This is the year, A.D. 843, that Turgesius was taken by Maelseachlainn (Malachy). He was then drowned in Loch Uair."[15] The "Book of Leinster" does not say that Turgesius was taken in battle, but those who do not believe Keating's story think he was. If he had been taken in battle and defeated, it must be admitted that it is strange that Irish annalists did not say so and give particulars of the battle. This omission makes it appear probable that there is some truth in the version of his capture as given by Keating, although it is altogether discredited by those best read in Irish History. Loch Ouel can be seen from the train on the Sligo division of the Great Western Railway. Passing as the glimpse of it is from the train, it is enough to reveal some of the beauties of this fairest of Westmeath lakes. But to see it properly one should wander by its pebbly shores, for not a yard of them is swampy, or ascend one of the hills of brilliant green that are on all sides of it. Loch Ouel has the great defect of being almost islandless. There are only one or two small ones in it. If it had proportionately as many islands in it as Loch Erne, it would be one of the fairest sheets of water of its size in Ireland. Belvedere Lake is a good deal larger than Loch Ouel, and its shores are better wooded, but part of them, in fact a very large part of them, is boggy. Its banks are adorned with gentlemen's seats, and in spite of the swampy shore on one side of it, it is a very beautiful lake. Loch Derravaragh is the most peculiarly-shaped of all the Westmeath lakes. It is shaped something like a tadpole, only that, unlike a tadpole, it is its head that is narrow, and its tail, or lower part, that is wide. It has bolder shores than any other lake in the county, some of the hills near it being almost mountains. It has hardly any islands, and its shores are wilder than any other of the Westmeath lakes. It wants the woods that do so much to adorn the swampy shores of Belvedere Lake; but comparatively bare as the shores of Loch Derravaragh are, it is a most picturesque lake, and some think it more beautiful than Loch Ouel. Both Loch Derravaragh and Loch Iron are formed by the river Inny, but it does not, as most rivers do, flow through the lakes it forms and feeds, for it flows out of them within a short distance of where it enters them, and the lakes extend in an opposite direction from where they receive their water. This is rather a strange fact in physical geography.
