There was a huge explosion and it created a large hole in the thick ironwood city gate. Broken pieces were thrown all over. The Empire's cavalry cheered from outside the city gate. A hurried drumming sound was heard as the horses charged in quickly through the gate in a long line. Even though the soldiers on the wall heard the loud explosion, they could not see and therefore did not know the gate had already been blasted open. But when they saw a big cavalry rush towards the city gate, the brave ones grabbed their bows and arrows and shot out a few arrows. As for the ones who were scared, they just ran down the wall tower.
