Lateral - Straight line sideways directly. Oblique - Straight line on a diagonal, either forwards or backwards. Circular - Any movement which describes a curved or circular path. As in Modern Fencing, start from Engarde, move forward with the lead foot and bring up the rear foot to come back into guard. Stay in the same guard as you began with.
Movement can be linear or oblique.
Similar to the Advance, move backwards starting with the rear foot and pull back the lead foot to come back into guard. Stay in the same guard as you began with. This has the advantage of getting your center and starting point closer to your opponent without endangering your body, but your mobility will be temporarily limited. This step can also be done retreating, or starting with feet joined and then stepping into a standard Engarde. Two Half Paces will take the same time and space as one Advance or Retreat.
