Campaign Tactical Map
The second role of guerrilla bands is to attack and capture French supply convoys.
The map above shows the situation on day 8 of the campaign. The French have advanced south and are preparing to attack Linares. They now have now taken six towns and established six depots. In doing so they have created six guerrilla bands.
Although the French have sufficient supplies, more than half of them are at the main depot in Probete (top centre). They can move a maximum of four days supplies up to three squares (by road) per day. Suchet orders Probete to move four days supplies to Baylen (centre of map). Because there are no guerrilla bands close enough to attack, they reach Baylen.
To attack a French convoy a guerrilla band must be in an adjacent square. Because they only have a maximum of three days supplies, the guerrilla can only remain in such a square for one day, and then have to return to their village to resupply.
The French do not have to detach an infantry brigade to act as escort to the supply convoy. Each convoy, whatever its size, has a combat ability of a conscript infantry brigade.
The outcome of the ambush is decided by the throw of a D6.
The attackers gain plus 1 if two guerrilla attack at the same time
They lose minus 1 for each 10% casualties.
1 – Guerrilla lose 10% casualties and rout
2 – Guerrilla lose 10% casualties, are shaken and retreat
3 – Guerrilla suffer no casualties but retreat without supplies
4 – Guerrilla suffer no casualties but retreat without supplies
5 – Guerrilla capture supplies
6 – Guerrilla capture supplies
Because it is so difficult to position a guerrilla band in the correct square to ambush a convoy, most guerrilla activity is against isolated garrisons.
