Where did germany began its war offensive and what happened there?

The Germans started by invading Belgium, giving the Belgium's only a few hours to stand aside or fight. Their goal was to drive hard through Belgium, capturing the Belgium's rail lines for resupply. Then make a hard left turn into France, bypassing all the French forts like Verdun By attacking a neutral country, the Germans brought the British into the war, along with the British fleet. It also enraged the American government, so Wilson looked the other way when Springfield and Remington shipped 500,000 en-field rifles to Britain. Britain used the riffles to build a two million man army, which allowed the Allies to match the Germans, division for division. The French paid a horrible price keeping the Germans down to a slow walk. Maybe 500,000 french died in the first year of the war. After 6 months, the Germans ran low on ammunition, dug in and focused on fighting in the east. If the Germans had waited for the French to attack them first, then Britain would have stayed out of the war. The German Navy would have sailed out and beat the snot out of the French. It turned out by going through Belgium, the Germans only gained a few weeks. If the Germans had attacked France directly, the French forts would have held them up only a few weeks, and then Verdun would have fallen to the Germans in 1914
