No retreat orders are necessary this round. The French army in Holland and the Austrian army in Belgium were forced to retreat, and as there was nowhere to retreat to they were both disbanded.
Russia failed to take possession of London as it moved out of London and therefore was not in possession at the end of a Fall turn.
Note: it occurs to me that Russia and Austria may have intended to cooperate in Austria's retreat from Belgium, using the fleet in the North Sea to convoy it to London. If this was the case, it wouldn't be allowed. The rules state that units needing retreat orders are to write those orders down. It implies that units not needing retreats do not submit retreat orders. A convoy order requires two orders to be submitted: the army to be convoyed and the fleet doing the convoying. As the fleet doing the convoying would not be retreating, it could not submit an order during the retreat orders phase, and any retreating army could not be convoyed to safety. Hence, the Austrian army in Belgium disbands.
Now that I'm reviewing the rules again I also notice that they state: "A dislodged unit must retreat to an adjacent province..." London is not adjacent to Belgium. This latter argument is a little more clear. In any case, both arguments stand.
