Well, it might not be quite so fanciful...I am no expert on this, but I do know that drums and bugles were used during battles to signal actions (charge, retreat, form a line, etc.).
Perhaps someone who knows about battlefield drum signals can weigh in...
But, it just may be a fanciful addition, and your initial comment might be on the money!
