The actual situation which MT is complaining about is shown below;
This pic is from behind Mike's regiments which are the blue and red ones towards the lower left.
His blue regiment is about to charge my blue regiment which is falling off the left hand side.
I have a falconet either side of the regiment angled inwards as shown in the next two pictures.
The Blue gun is aimed at the red regiment in-front of the charging regiment.
The Orange gun is aimed at a unit of horse to the left of the infantry.
