In reply to Only a hill:
Alisdair MacColla and the Highland Problem in the 17th Century, David Stevenson.
The Campaigns of Montrose, Stuart Reid
For King and Conscience (John Graham of Claverhouse), Magnus Linklater & Christian Hesketh
Rob Roy MacGregor, W H Murray ( a lot of social history in that)
Glencoe and the Indians, James Hunter (perhaps slightly off topic as much about West Highlanders in America as in the West Highlands.
I've got more but I'll have to check the back shelves, but those 5 stuck in my mind, number 1 is superb but needs 2 as a little bit of a counterweight. Bill Murray's book is very good. In fact they all are.
Hope that helps,
