The Flag in the Wind: The Story of the National Movement in Scotland

The Flag in the Wind is worth a look to get an insight into the thinking of one of the most influential figures in the early nationalist movement. Although it has its flaws and partisan perspectives on elements within the movement this is more than compensated for the wider perspective MacCormick takes on Scottish history, politics and culture. It is one of the few first-hand accounts we have of Scottish politics in the immediate post-war era.

An excellent review is in Bella Caledonia
