[Shostak]

The rules could definitely be clearer, but I think that they suggest that entering into HTH always happens during the movement phase, and the actual attacks occur during the action phase. The only exception to this is that if an attempt to initiate HTH is repelled with a roll of 6, the defender gets a free hit on the attacker that is in addition to a normal action. If one is extremely lucky, one could repel up to five HTH attempts and get in a normal attack for a total of up to six attacks in one turn.
