Chamberlain made a short statement as he got off the plane coming home from signing the Munich Pact, in which the Sudetenland was more or less handed over to Hitler in exchange for his promise to never, ever invade Czechoslovakia. He gave the speech again at the prime minister's digs at 10 Downing St.

He was surrounded by huge crowds of cheering Brits, who were celebrating what everyone believed was a big accomplishment that would prevent war with Germany. Chamberlain was confident the Pact would hold: "We regard the agreement signed last night and the Anglo-German Naval Agreement as symbolic of the desire of our two peoples never to go to war with one another again" (source).

Oops.

In his speech on September 30, 1938, he famously declared "My good friends, for the second time in our history, a British Prime Minister has returned from Germany bringing peace with honor. I believe it is peace for our time…" (source). The "peace for our time" was a reference to Benjamin Disraeli's address after returning from the Congress of Berlin in 1878. Although that quote is often confused with "pizza on time," which everyone knows is totally impossible.

This moment was the high point of Chamberlain's career, when everyone, including himself, thought the crisis had been resolved and war had been averted. As we all know, it wasn't—and within two years Chamberlain would resign because of it.
