Hmm. Of course 10th century Norsemen didn't keep
records - but you could imitate the later history style.

Varð þar bardagi mikill. - A great battle occurred there.
Fell þar Óláfr konungr ok mart af liði hans. - King Olaf fell there and much of his force.

For formulaic annals Old English is much better, though..

The New Anglo Saxon Chronicle, currently maintained by
Anthony Appleyard, I find quite interesting.
