Easier to break as it is strung out and a bigger target, suggest you read David chandlers book " Campaigns of Napoleon " if you can get a hold of it .
It has long been out of print but still can be got in the national library to special order. Everything about tactics of the time from grand tactics down to battle field and individual battalion .
Every battle Napoleon fought ,artillery make up, regimental , battalion , cavalry squadrons ,heavy and light . For instance heavy cavalry riding boot to boot and never really going quicker than a fast trot and arrving en mass .
The book is very large and covers everything . An essential read for any student of napoleonic warfare .
