Analysis indicates, however, that not all of the men wished to be a part of what was swiftly becoming a pirate raid; John Wynter specifically spoke against it. Kelsey concludes that Drake wanted to set a stern example against indiscipline in the crew; his choice to hold Doughty's trial on the same spot where Ferdinand Magellan had executed his mutineers could hardly have been coincidental. Nevertheless, the rest of the circumnavigation was plagued by bouts of dissent. In January 1580, when Drake became stranded upon a reef off the Celebes Sea, the ship's chaplain Francis Fletcher gave a sermon connecting their woes to the unjust demise of Doughty. For this action, Drake not only relieved Fletcher of his duties but chained him to a hatch cover and, despite his obvious lack of authority to do so, pronounced him excommunicated.
