Artillery being charged.

Answering in reverse

2) No, casualties caused by closing fire do not count towards Combat Resolution, but they do count in the following break test if that unit loses the combat.

1) the combat is a draw. Neither side has to take a break test because neither side lost. Nor did either side become shaken (stamina level reached) so again, no break test required. After a drawn combat, any unit that is shaken must take a break test. It does not mean that the other side won, it is still a drawn combat. Indeed, both sides could be shaken and so take a break test.

after a drawn combat, all cavalry retires. No break test required, they just fall back.

Hope that clarifies for you.

The FAQ that Garry refers to…

The Quick Reference Sheet (QRS) states that a break test is required for units suffering artillery casualties
from closing fire (b. Test if Shaken or suffering artillery casualties from closing fire). Because the best
result that cavalry can get from such a test is ‘retire’ this makes it practically impossible for cavalry to
charge home onto artillery (they would have to suffer zero casualties from 3 shots per cannon requiring 3+
to hit and -2 saves).
This is a case of a rule being added a little late in the day and not quite being explained properly. Originally we had things
arranged so that only Shaken units tested – and this works well enough. After a while we felt that units taking artillery
casualties on the way in – but not being Shaken – should also have to test their resolve to see if they charged home. What we
failed to make clear is that this test should be taken using the Shooting results on the Break Test, and not the Hand-to-Hand
results as you would for a Shaken unit. As the testing unit would have charged into position at the point the test is made, a
result of ‘unit holds its ground’ means that the charge is successfully completed and the charger and artillery are engaged in
combat. With the usual -1 modifier for artillery casualties this means a test score of 7 or better will see the unit charge home
successfully.
Some players do prefer to use more artillery that we typically might – and the relatively narrow frontage of artillery pieces
does make closing fire from massed guns even more effective than reality would suggest. Where a unit charges onto multiple
guns we’d recommend allowing only a single gun to shoot closing fire – this is plenty dangerous enough without making such
attacks suicidal

Mike, I always wondered why the break test for Closing Fire used the Hand to Hand result, especially as the test, if taken at all, happens before any close combat had occurred. However, this has always been the case, even in the original rulebook. You just don’t charge artillery head on with cavalry because they’ll never make it. Skirmishers are the best thing for a frontal attack on artillery, really.

In Hand to Hand, Artillery is very weak and vulnerable. Every break test result is Break and it cannot be supported, so closing fire is the only real chance it has at surviving contact with the enemy.
