The conduct of Preston throughout the whole of these proceedings showed the weakness of the Confederate position as well as of his own character. First he gave Ormonde to understand that he would prevent O'Neill from marching southwards, and then he let the nuncio persuade him to join forces with the northern general in the attempt to intercept Ormonde and in threatening Dublin. On August 26 he wrote to invite the Lord Lieutenant's commands as to the disposition of troops to prevent O'Neill from entering Leinster. On September 5 he excused himself from personal attendance. On the 17th he lamented that clerical threats of excommunication prevented him from obeying any of the Lord Lieutenant's orders. On October 10 he found that the peace published in his camp and by his authority was 'destructive to my religion and liberty of the nation,' and contrary to his oath as a Confederate. On the 21st he swore solemnly to aid O'Neill in attacking Dublin, to 'use and exercise all acts of hostility against the Lord Marquis of Ormonde and his party,' and to damage him in every possible way. Digby, who was a sanguine man, thought it possible to kidnap O'Neill and Rinuccini and carry them to Dublin, and to spike Preston's guns, and he was also inclined to believe that something might be done with that vacillating general. Ormonde was less hopeful, but his patience was inexhaustible, and he resolved to make another effort, and Preston took care to let him know privately that he was not really irreconcilable, and would not join O'Neill, and that if he captured towns or castles it was only to prevent the Ulster general from getting them. Clanricarde was sent for from Portumna, and came to Luttrellstown, where he was in a position to communicate with all parties.[102] [Sidenote: Extreme demands of the nuncio.] [Sidenote: Ormonde's distrust of the Confederates.] [Sidenote: Agreement between Digby and Preston.] [Sidenote: Ormonde does not adopt it.] [Sidenote: Proposed treatment of Protestants.] [Sidenote: Dublin cannot be taken.]
