 After the rebellion was defeated, Roger of Poitou, Alan Rufus, Odo of Champagne, and Walter d'Aincourt were sent to persuade St-Calais to surrender.After a lengthy parley during which they waited outside the castle, St-Calais agreed to surrender his person and stand trial, but only once they signed a complex document promising safe conduct before, during, and after the trial.Alan Rufus played a significant role in the subsequent trial of St-Calais, which commenced on 2 November 1088 at Salisbury in Wiltshire.
