2950 assistance

Anyone have the timeline of the northern area during the war of the ring? I know it is listed somewhere that the elves and dwarves in the north were fighting at the same time the men fought in the south, but I would like as many specifics as possible (both from ICE and from the appendix info is great)

The area of most interest is in and around Rivendale, but info on mirkwood, etc is helpful.

Thanks,
Ken
