Gurwood moved straight on to editing the papers relating to the Peninsula War but progress was slowed by the Duke's political commitments and by Gurwood's mission to Spain. There was a further serious consideration: the Duke was concerned about the consequences of publishing material relating to such recent events and to persons still living. When he returned corrected pages to Gurwood on 30 July 1835 he commented that they were as interesting as those about India but doubted whether they should be published. He had cut out some parts and needed to look again at others with a wish to avoid 'a Controversy with Nations as well as Individuals which will not be an agreeable pastime in my old age.' Personally, he was confronted with the issue of the Convention of Cintra where he had known that he 'was the object of party violence, that the wish and intention of the Party at that time was to have a victim and that I was the Person fixed upon.'
