Lines of Battle: Quatre Bras 1815. Brunswick hussar.
Just my thoughts, but area 17 is not adjacent to 5 across the river, but adjacent to Albuera across the river. Same with area 16. Dotted lines would have helped better define the area of Albuera.
You're right. 17 is only adjacent to Albuera across the river.
No approaches on the river or with close terrain (Albuera).
