You ought to read Corelli Bennet's 'The Swordbearers' for a truly eye openning account of the ammount of folly that deadlocked the German advance into France.
Here are a few of the 'dirty secrets' of World War One. That country that everyne decries as being 'stupid' for being over run, Belgium, wasn't - - - - offered nothing in return for letting Imperial Germany use Belgium as a Highway - - - King A;bert, unfairly ignored by Hollywood, stood in the way and helped to slow the advance. Then Belgium under the leadership of Albert clung to a strip of territory and contined to tie down German forces..
Another dirty secret. Much as I and millions others like to rididicule the French, the truth is they were brave & well led and would not let Germany roll over Paris..... The French had the best short range artillery and were tenaciious as H^ck wrecking German plans for a swift invasion.
Britain also frustrated German plans. Standing in the waym, getting in the way, holding down German troops. Germany half hearted hoped the British would sit this War out, not aware there were reasons why Constitutional Monarchy Britain chose to side with 'Democratic' France.
Oh and this dirty secret annoys the Aryan Purist. The Germans had 'leadership' problems. Van Moltke was twisted this way and that by an indiscive Kaiser and his own staffing abilities were not that great.
Communications also dogged the Germans but what reallly jammed things up was the Organizational need for Three Leading Generals UNFORTUNATELY Those three Generals did not get along and so like an American football team when the coach the quarterback and the management are at odds odds are stalemate or worse.
And finally - - - TECHNOLOGY outstripped warfare. World War One was that rare moment in time when mankind hit a brickwall in warfare. Machine guns and bigger bombs and submarines and mines and aireal machines and above all MOTORIZED VEHICLES made it possible to kill more people more effiiantly.
Peace........................ ppppppffffftttttzzzzzz (ah)
