Ok I have 2 BG's (one CATS on EL)that have charged a MI roman unit both have won close combat I have caused 1 hp3b so -1 and 2 or more hits than recieved so another -1 (-2 so far) Now I have mounted that have beaten MI in open so another -1 and ALSO I have EL beating MI so another -1 right ? for a total test of -4 ? is this correct?

-3 The section says 'one of' so you cannot count both the elephants and the mounted v medium foot loss.

THanks totally missed that !
