I've never played a war simulation before...so pardon the question.

I played the Tutorial mission, thinking I knew enough, and then started the English one- normal difficulty.
I won the first battle, but the second one confused me, and I got decimated.
1) Why do I have 2 victory symbols, and the French have none? What do the 'V's' connotate? Why 2 'V's', and not 3, or 1, or 0?
2) I assume, I have to protect these 'V's'- lose 'um, you're done. So...is this an offensive, or a defensive battle? Is there a way to tell?
Thanx!
