Battle of Einsamenhügel - Aftermath

IT was an exciting battle and very much in the balance until near the end.
Indeed at first the Pragmatic Army appeared in serious trouble as the cavalry on its left wing disappeared, but in the end the superiority of British musketry turned the tide.
The advantage we both thought I would get from siting my guns on the Einsamenhügel turned out to be illusory as their choice of targets was quickly reduced by my advancing foot.
Maurice, on the other hand, cleverly positioned his guns so they could support his right-flank attack without being masked by their own troops. However, this was not enough to turn the tide.
One particularly realistic touch came after Maurice's right-flank horse triumphed and seemed poised to swoop down on the unprotected flank of the British infantry. I was able to foil this by advancing the Hanoverian foot from the second line - their firepower deterring the French cavalry from attempting a charge.
However, we found that generally there was not enough incentive for players to maintain a historically-accurate second line.
Accordingly, I am tweaking the morale section of my rules by adding this clause:
A unit adds 1 to its morale throw if it has a friendly unit directly behind and able to reach it in two turns by normal movement, ie in the formation it is in and without any movement-variation addition. Exception: light infantry and artillery units cannot give support in this way.
