Churchill explains that the major material losses will "further impose a further delay on the expansion" of Great Britain's military strength. What is Churchill trying to persuade all of Great Britain to do? Support your opinion with at least one essential detail from this section.

This quotation is a part of Churchill's famous speech "We shall fight on the beaches". Churchill said "But our losses in material are enormous. We have perhaps lost one-third of the men we lost in the opening days of the battle of 21st March, 1918, but we have lost nearly as many guns-nearly 1,000 guns-and all our transport, all the armoured vehicles that were with the Army in the North. This loss will impose a further delay on the expansion of our military strength. That expansion had not been proceeding as fast as we had hoped". He also adds "I have, myself, full confidence that if all do their duty, if nothing is neglected, and if the best arrangements are made, as they are being made, we shall prove ourselves once again able to defend our island home, to ride out the storm of war, and to outlive the menace of tyranny, if necessary for years, if necessary alone. At any rate, that is what we are going to try to do".

So, in conclusion, Churchill in this famous speech was, on the one hand, explaining the extend of the damage in the Dunkirk disaster (the specific and major losses), but on the other hand he is infusing confidence in the British people, making clear that, despite the powerful enemy, the UK will never surrender.
