What happened at Merryton?

When the Miss Bennets and Mr. Collins go for a walk to Meryton, they are introduced to an officer in the regiment named Mr. Wickham. They also run into Mr. Darcy, and when Darcy and Wickham meet both seem to be extremely uncomfortable. Mr. Wickham immediately shows a partiality for Elizabeth and they speak at length. Wickham tells Elizabeth that the reason for the mutual embarrassment when he and Darcy met is that Darcy's father had promised that Wickham, his godson, should be given a good living after his death, but that Darcy had failed to fulfill his father's dying wishes and had left Wickham to support himself. Elizabeth, already predisposed to think badly of Darcy, does not question Wickham's account. When Elizabeth tells Jane Wickham's story Jane refuses think badly of either Wickham or Darcy and assumes there must be some misunderstanding. Please see source-link below.
