<u>Churcill pronounced those words as part of an speech in the Munich Confederence, also known as Munich Betrayal, that took place in 1938.</u>
After intense negotiations, leaders from France and UK allowed nazi Germany to annex the region called "Sudetenland" in Czechoslovakia, by not sending any troops there. Morover, the French-Czechoslovak alliance was dishonoured.
Hitler had already started his policy of "Living Space", which aimed to gain the territories that the supreme German race deserved, according to his Nazi ideology. He had gained control over territories without opposition, and Sudetenland was just another one. This is why Churchill said that Hitler got “them served to him course by course”.
Answer:
serfdom, condition in medieval Europe in which a tenant farmer was bound to a hereditary plot of land and to the will of his landlord. The vast majority of serfs in medieval Europe obtained their subsistence by cultivating a plot of land that was owned by a lord. This was the essential feature differentiating serfs from slaves, who were bought and sold without reference to a plot of land. The serf provided his own food and clothing from his own productive efforts. A substantial proportion of the grain the serf grew on his holding had to be given to his lord. The lord could also compel the serf to cultivate that portion of the lord’s land that was not held by other tenants (called demesne land). The serf also had to use his lord’s grain mills and no others.
