Germany thought they could defeat Britain and theunited states by using submarines but the united states built so many new ships thatmade Germany not able to sink all ships so that’s why submarines did not winthe war for Germany so then Germany tried to defeat Britain by bombing their cities but they did not succeed. In1917 Russia quitted the war this must have given Germany an eventual victory butthat’s not what happened, by July 1918 the allies were winning the war so Germanytried to reach France but the allies defeated Germany in the Argonne forestbattle. World war 2 began in September 1939 with the invasion of Poland by Nazi Germany then Britainand France declared war on Nazi Germany after the invasion, “This morning the British Ambassador in Berlin handedthe German Government a final Note stating that, unless we heardfrom them by 11 o’clock that they were prepared at once to withdrawtheir troops from Poland, a state of war would exist between us”Neville chamberlain, 1939.
