In the story by Charles Dickens about the French Revolution A Tale of Two Cities, Charles Darnay received a letter from a well-liked servant who was also a doctor, Gabelle, who is also the father of his future bride to be.
Gabelle had been cruelly imprisoned at La Bastille and Darnay was asked to go help rescue him with Gabelle's daughter. It was a very dangerous time as the revolution was already showing signs of imminence and the situation would be a very sour one for anyone. In fact, Darnay paid dearly for his decision of going to France and he became imprisoned himself.
He wanted to rescue Gabelle and he didn't want anyone else to keep calling him a coward. If you remember, before Stryver gave the letter to Darnay, he called Evremonde a coward. The reason why is because when Charles left France, he never came back to re-claim his Chateu. Stryver along with most of the French aristocrats thought he was a coward because they thought he was to scared to go back into France. I'm sorry if this is confusing....I got a headache myself after reading this.
He went back to France because an old family servant, who was a friend to him, sent him a letter begging for help. This servant, Gabelle, had been imprisoned and he was asking for Darnay to come and deliver him.
