One of Eugene's divisions go intercepted by Russian cavalry using order conversions to Attack. When this happens we assumed that the objective for the force (i.e. the Russian cavalry corps) remained the same and the objective - i.e. one of Eugene's divisions only applied to the formation - in this case a Russian cavalry brigade - that was subject to the order conversion.

Cavalry converting to attack [A] is an implied exception to the requirement that all movement must be towards the Force’s objective, per 4.1.1: cavalry may convert if they have a target within 45o and one full movement and then are immediately moved to contact with that target. Once the conversion move is completed, the cavalry are just another Formation on an attack [A] order, so subsequent movement would be required to comply with the attack [A] order per 3.6.1.
