Final answer:
The main claim in Churchill's speech is that Britain will continuously fight against Axis powers without surrendering, and his supporting claims illustrate the various scenarios in which Britain will continue to resist the enemy.
Step-by-step explanation:
The main claim in Winston Churchill's never give up speech, often referred to as his "We Shall Fight on the Beaches" speech, is a defiant declaration that Britain will fight against Axis powers in every possible scenario and never surrender. This speech, delivered during World War II, aimed to fortify British resolve in the face of overwhelming odds. The supporting claims revolve around various scenarios of resistance--fighting on beaches, landing grounds, in fields, streets, and hills--to convey the comprehensive and unyielding nature of British resistance against the Nazi invasion.
Churchill's rhetoric throughout war time served to bolster British morale and was characterized by its dramatic and resolute nature, which became particularly poignant as Britain faced the threat of Nazi Germany.
