"Just at the bit": April 1757
This was a quiet pair of turns, so I'll mostly concentrate on background stuff. The final part of the update is a discussion of the reinforcement and replacement cycle, those only interested in the AAR can easily skip that.
One main job in this period is sorting out all those Austrian units that pile up at Wien and Pressburg over the winter. They mostly unlock about now (some a bit earlier, some a bit later).
Here I'd sent Picolomini and Kollowrate back in the winter, and Nadasdy appeared (you get him by event) to help out. Charles is back there to make an army.
Now my plan was to use Picolomini as the heart of a force to campaign on the Oder. As you get more brigadiers later, the basic organisation of this army is a bit of a mess for now.
In the meantime the main bulk were sent to Prag
Another job (these turns are a bit 'administrative' for the Austrians) is to do with the HRE/Bavarian forces. But till they unlock you cannot do much to allocate brigade command etc.
One choice is what to do with 5 brigades of quite useful units. You can send them to Bohemia where they join the Austrian army. This will annoy the French and cost you VP. Allow them to mobilise at home (the south of the map, about 3 turns marching from any use but you get more EP for this). Or, as I tend to do, at Nuremburg with the rest of the Bavarian army.
And finally the French unlock. Now I started with quite an ambitious plan to leapfrog Wesel and go for Munster at the same time. In reality you can't do this due to supply problems, but this was my original set of orders.
By late April, the Prussians have entered Bavaria near Bayreuth but the passes have blocked behind them. So I think that was their chance to really hit the force at Nuremburg has gone (note its still locked). Especially when the Wien reinforcements start to arrive at Prag, making Daun much more dangerous (I could hold the passes and invade Saxony while the Prussians were in Bavaria)
The war in the north hots up
But unusually for us, the overall death rate has remained very low.
Which sort of leads me to a short digression on reinforcements and replacements. Narwhal has already covered the essentials in
Learning from Prussia and, as far as I know, all that is still valid. So this is purely from the Austrian perspective.
In essence you get reinforcements from 4 sources.
For example a large French force (in addition to the above) unlocks in early Autumn 1757 and the final batch in early Summer 1758 (I forget the exact dates). The Russians receive an additional corps this way in the Winter of 1757-8. Now these are 'on the map' at the start but unuseable till they unlock.
You receive a lot, mostly Austrian by scripted events
The bulk of these pile up around Wien and Pressburg over the winter of 1756 and unlock in early Spring 1757. As above, its a good idea to preposition Charles and some corps commanders to sort them out and move them to the front. Actually you need combat ready corps to go to Prag as it maybe an active battle zone. You get another 8 battalions in late summer 1757 and 4 (I think) in Spring 1758 as the Empire strips its forces in the quiet sectors (remember that notionally the Turks are in alliance with Prussia so the forces in Croatia and Hungary are essential in case of active war breaking out). The French get 3-4 brigades of Saxons in 1758 by the same method.
By spending EPs (Engagement Points)
.
Usually for the Austrians these are hard to come by (not least you often have them stripped off you to restore your National Morale (NM). You mostly get 1 of two things this way. You can spend them on replacements, these go into a stockpile and are then used to replace losses in your field battalions. This is the only way to replace losses in your cavalry, artillery and light infantry, and you have separate pools for every nationality.
You can also use EP to buy 'mercenaries' for France. I think these are good value (10 EP+60 cash) gets you 6-10 battalions (incl 3-4 cavalry), usually with their own brigade commanders. You can also spend EP to gain more Swedes, the 25EP 'large reinforcement' brings 10 brigades (around 30 battalions) but with no corps commander, so you will need to send someone with the 'HRE' trait to help out with the command structure.
Finally, you have a stock of conscript companies and money
.
Conscript companies come from cities you own, from Prisoners of War and returning losses (differential rates for those lost to attrition and those lost in battle). For Prussia this is an easy source of new units (as they have no cash constraint), for Austria, your cash problem limits the ability to draw these down. However, they are 'generic' and can be used by all your nationalities. With these you can build almost any regular battalion – infantry, cavalry, guns, supply wagons or specialists.
Or you can build depot battalions (either regular or elite).
Once these 'finish training' they go into your replacement pool and allow you to rebuild losses (but only for the appropriate type of infantry). For the most part, I concentrate on depot battalions as you have a shortage of brigadiers and can't often make the best use of the field army you have. You can, for example, build about 8 depot battalions for the HRE, Bavarian and Wurtemburg army at Nuremburg so when it unlocks it is quite strong. But this rather depends, if you have had a brutal autumn in Bohemia defending Prag, then quite often the Austrians have to be your priority.
This is from much later in the game, actually the current turn we are playing, and shows the view for me. I've never worried about 'war supplies', as you can see I have a lot of reserve manpower (conscript companies) and very little cash/EP. As an aside, if you ever occupy Berlin, you can levy a rather nice tax on the inhabitants --- or just it burn it down
You can see this using the 'supply' map mode as;
Actually I very rarely use the other map views as they are not that essential in RoP. But this shows how Wien is critical to my war economy. In truth if this is ever threatened then I lost the game a long time ago.
Now in theory this means you can wage economic warfare, in truth I scarcely ever look at this map view as by the time I am taking or losing economically critical cities its also probably a clear victory in any case.
