Song of Roland Laisses 1-50

Thus far in The Song of Roland, we have seen Marsille devising his plan to get Charlemagne  out of Spain, even at the cost of twenty of his people. Charlemagne sends Ganelon to give Marsille his letter, but once there, Ganelon speaks with Marsille's chief adviser, and makes a pact with him to kill Roland and end the war. Ganelon then speaks blasphemy to Marsille on Charlemagne's account, but convinces Marsille to go with his plans to kill Roland.
