Oops!

Costa e Silva & Madeira were quite right....the original
WAS centred incorrectly!
I have fixed it and the CORRECT version is now in the first post.

- surely the Companions too must have had some sort of back-up weapons?
Well, to quote from the Roman historian Arrian:-
"At the battle of the river Granicus, Alexander's lance was broken. He called on Aretis, one of his grooms, for another, but Aretis was himself in difficulties for the same reason, though still fighting gallanty with the remaing half of his weapon. Showing it to Alexander, he called out to him to ask someone else, and Demaratus the Corinthian, one of Alexander's personal bodyguard, gave him his lance. The fresh weapon in hand, he caught sight of Mithridates, Darius' son-in-law, struck him in the face, and hurled him to the ground.
Now Spithridates had his sword raised, ready for a blow at Alexander from behind; but Cleitus, son of Dropidas, was too quick for him, and severed his shoulder sword and all."
From this account we can see that Alexander prefered to have another lance rather than draw his sword, and that Aretis would sooner fight on with a broken lance than draw his own sword.
However, Cleitus couldn't have severed an arm with a lance, so must have used a sword himself.
So I think I'll leave it as it is, although one day I would like to add a lance to the Civ3 Knight for the attack 'A' just as you suggested.
(In the week or two it would take me to remove the lance and add a sword, I could make a new unit....such as the Numidian Horseman that Costa e Silva reminded me about, which has been temporarily put on hold while I finish another important project)
