In case anyone's confused, the Denethor here is not the same guy that appears in Lord of the Rings, which is set about 10,000 years later.
For this scene, I'm imagining that every single elf in Thingol's army fights like Legolas in the Peter Jackson movies, or better - and yet they still lost (or won only a Pyrrhic victory). Though as I mentioned in the comments last time, it's possible that what the peaceful, unwarlike Sindar consider to be unbearably high casualties, later and more determined Elven armies would shrug off as acceptable losses.
Beleg is, let's say, rather over-confident and reckless. Let's hope it doesn't get him into trouble.
