A number of members of the crew kept detailed journals of the cruise, and one officer even sketched entertaining watercolors of scenes and incidents along the way. Added to official correspondence, the result is a well-documented trip. One episode stands out above all others. In early May 1845, the ship anchored in Touron Bay, Cochin China (now Vietnam). On the second day, Percival received a note from a French missionary, Bishop Dominique Lefevere, saying the local authorities had him under arrest and condemned him to death. Within an hour, Mad Jack led 80 well-armed men ashore. Percival left a letter for the king of Cochin China demanding the bishop's release. To make his point, he returned to the ship with three mandarins held as hostages. The next day, Percival pressed the issue by capturing three junks belonging to the king, and moved his warship closer to the local forts. On the following day, the prize junks attempted to escape, but were recovered after a brief skirmish. Percival, as well as the Cochin Chinese themselves, denied the gunplay resulted in any casualties. Nonetheless, a rumor of fatalities continued into the 20th century when the confrontation became known as the first armed intervention by a Western nation against present-day Vietnam. In any event, a short while later Lefevere gained his freedom and the French credited the American effort for saving his life. King Louis Philippe intended to reward officers and crew. But political turmoil interfered. Since the king "took a hurried journey from his capital, ... no recognition of their services was ever received by the American tars." Their compensation went "over the walls of the Tuileries gardens" as Louis Philippe escaped to London.
