Field of glory V3 rules question

[Bobsebotka05]

Hi a question about contacting a fresh unit after a pursuit? My cavalry was contacte by one stand of heavy foot offensive spear. So in the next bound we did an impact phase charge attack. So the question is, does the spearmen get to step a second ɓase forward? And if so do I have to turn my whole battle group? Reason for asking is from a purely random diceroll, I was told I had to turn to face which disadvantaged me because the cavalry battle group i was aiming to engage then charged me in the side. Would the original contact have been 3 dice apiece, 5 to 3's in spearmen favour, but allow me to charge the cavalry i was facing off against? Thanks in advance.
Bob.
