ok thanks lex , and for hill how do you play in your games , for example my hills are just a raised plain ; so if i put unit on the edge of mountain they are upper than enemy but if they lost combat ,and are pursuited, all are on the same level. the next combat then i considered no defense bonus. Is this a right method to use hill or is better to count defender on upper level (and so hit them on 5) until they reach the crest ?(or the medium line of the scenic)
