midnight
`` Each knight escorted his lady through the triumphal arches erected in honor of the Generals who were present , along the long avenue lined on both sides with the troops and the colors of the army . At the third arch , which was dedicated to General Howe and which bore on its top a huge flying figure of Fame , we entered the great Hall . There refreshments were served and the dancing began . It continued until midnight . The windows were then thrown open and we witnessed the wonderful display of fireworks . And then the supper ! `` Gorgeous , of course ! ''
