[Gwathagor]

One could conceivably estimate the population of Laketown, based on the size of the lake and the extent of the industries thereabouts and the need for labor, but how do we begin to guess the size of the Elvish army? Tolkien's description of the caves doesn't give us much to go on. However...Thranduil only had one butler, so I suppose he couldn't have had TOO many people living down there...and they certainly weren't all warriors. I might be inclined to say that Groin's estimate of around 1000 soldiers in the Elvish army might even be too high. I'd guess around half that.
