 Gregory wrote several letters to his father at this time, detailing the difficulties of the crossing from Dover to Calais (a twelve-hour journey), reporting that many of the gentlemen with him were "extremely vexed with sickness" and assuring his father that he and the Lord Admiral were not among them.More than likely, this was his first time on board a ship and away from the English mainland.He describes his impressions at the first sight of Calais, how he has seen the castle and the blockhouses and other fortresses and recounts the delights of the feasting, entertainments and jousting while waiting for Henry VIII's new bride.
