Why did the belgiums hopes to resist the Germany by using fortress fail?

Belgium's hopes to resist Germany using its fortresses failed due to the rapid and overwhelming strength of the German military during World War I. The Germans employed a strategy of encirclement and utilized heavy artillery to breach the fortifications quickly. Additionally, Belgium's fortresses, while initially considered strong, were outdated and could not withstand the modern warfare tactics and technology employed by the Germans. This allowed Germany to bypass and capture key locations, leading to a swift occupation of Belgium.
