The Hougoumont battle has often been characterised as a diversionary attack to cause Wellington to move reserves to his threatened right flank to protect his communications, but this then escalated into an all-day battle which drew in more and more French troops but just a handful of Wellington's, having the exact opposite effect to that intended. In fact there is a good case that both Napoleon and Wellington thought Hougoumont was a vital part of the battle. Certainly, Wellington declared afterwards that "the success of the battle turned upon the closing of the gates at Hougoumont".
