no you can't, 1 attack per round regardless.
basically round 1 the only thing that happened was movement.
Round 2 the first 2 opponents decides to use low initiative charge attacks, so one got counter hitted, and another got juggled. but speed used a low attack and his opponent also happen to use a low attack with the same initiative, so neither scores a hit.
Round 3 we are still waiting on speed, but jacob combos and vlad clean hits his enemy and defeats him.
