De la Broquière set off for the Holy Land in 1432 for the purpose of spying out the possibilities of a new crusade to be led by the Duke of Burgundy. He returned overland, through the Turkish Empire, alone. His observations of the land, the people, the rulers, the food and the customs make fascinating reading. There is also a long section on the organization and tactics of the Ottoman Army, and the ways that the Europeans can use to defeat it. De la Broquière is a highly competent spy and a very observant tourist.
