I would like to know what was creating the 2nd Report heard moments after firing the Canon ? Was it an Echo or and Explosive Canon Ball or was the Ball actually hitting something, like a hard wall ?

Did they load it with a canon ball, I couldn't tell what they were aiming at so it was hard to tell, but the area looks closed in with all the trees so the sound was more than likely a echo
