[Son of Númenor]

Why did the annals of the Men make no mention of the Hobbits? Oh, I bet they were there alright. At the battle. But maybe memory of them faded as contact dwindled or their importance to Men lessened as Men regain their strength.

This is just a quick addendum to what Bêthberry and others have said concerning possible reasons why hobbit bowmen (bowhobbits?) at Fornost were not remembered in the annals of Men. A major fact to consider is that the battle against the Witch-King in Fornost was the battle that brought an end to the North Kingdom. When a kingdom is vanquished like Arnor was, it is not surprising that detailed records are not kept by those defeated, of the battle which caused the defeat. It would have been easy to overlook a few short archers when finally a written account of the battle was produced who knows how many months or years later.
