Detailed explanation-2: -Of course, Belgians refused to let them through, so the Germans decided to enter by force and invaded Belgium on Aug. 4, 1914. By doing so, they violated the Treaty of London, which is why Great Britain, that was bound to guard the neutrality of Belgium, entered the war.

Detailed explanation-3: -The German juggernaut smashed its way into Belgium on August 5, initially targeting Belgium’s line of defensive fortresses. The Belgian army was forced to retreat and by August 20 the Germans entered Brussels on its way to France. The Belgians elected not to defend the city and the Germans marched through unhindered.

Detailed explanation-4: -Britain and its Empire go to war Germany’s invasion of Belgium tipped the balance for Britain. At 2pm on 4 August, it issued an ultimatum demanding Germany withdraw its troops. At 11pm, the deadline passed without a reply. Britain declared war.

Detailed explanation-5: -The official explanation focused on protecting Belgium as a neutral country; the main reason, however, was to prevent a French defeat that would have left Germany in control of Western Europe.
