Rules - Fortifications and Fieldworks

Defence Values of Buildings and Fortifications

As with firing at troops a score of 7 or better is required by artillery firing ball to remove 1 strength point. If troops are in the buildings use the same dice score to determine the damage to the building ignoring the deduction for cover. To equate with cover 2-4 strength points = soft cover, 5-8 strength points = hard cover, 9 or more = fortified. Therefore as building are damaged the cover they provide is reduced.
As with firing at troops a score of 7 or better is required by artillery firing ball to remove 1 strength point.
Strength Points:-
Wooden Bridge (per 100mm)...................... 3
Stone Bridge ditto.......................................... 6
Wooden Building (50mm x 100mm)........... 4
Stone Building ditto....................................... 8
Wooden Building (100mm x 100mm)......... 6
Stone Building ditto....................................... 12
Timber fieldwork (per 100mm).................... 6
Earth and Timber Redoubt............................ 10
Timber Stockade (per 100mm)..................... 8

Field Engineering

In most cases fieldworks have been constructed before a battle commences, but if necessary they can be constructed during a battle. 1 wagon can hold enough tools for 1 close order infantry unit. This enables them to dismantle 1 strength point every move or construct 1 strength point of a fieldwork every other move.

Demolition

1 wagon can hold 6 charges. The sequence is as follows: spend 1 movement phase laying the charge, move away on the next movement phase, then test for effect on the firing phase following moving away. For effect roll 2d6 if it is greater than the targets defence strength points it is destroyed. If more than 1 charge is used it takes 1 extra move to lay each charge and use one extra d6 per additional charge to determine the effect. If any unit is within 3" roll 2d6 for effect as if firing. Increase the distance by 1" for each additional charge used.
