In the Gulf Dunlop does his stuff - yep.. I am not sure who will be holding New Orleans by the time the war kicks off. If it is the Union does Dunlop try to take it?
The defence of New Orleans is tying down 20,000 CS Troops (the Union ISTR have taken some outlying islands as naval depots). With Dunlop sweeping through these can be redeployed north to face Hallecks "Army Group of the West", giving the CS numerical advantage.
One big squadron to take out Monroe and raid the Chessapeake into ruin. Blockading groups at both ends of Long Island. Also need blockading group at boston and points north.
cf the Hydrographer Report.
Don't see what you have the British up to on Superior and I don't think they can get to St. Louis in a short war. I see all the lakes in Union hands and I can't see the Union advance up to Kingston on your map.
That's the limit of the Canadian Rail net (I do a similar indication for the Union), it's impossible to sustain major forces west of this.
The Union is at Kingston, I just drew the arrow a little south (in MS Paint!).
I can't credit the British advance from Fredricton. The country is too rough and the Union has too many railways and river it can used to interdict the advance. Not going to happen. What I can see is a landing to secure the end of Maine as I have suggested. For a more forceful British attack I would suggest the old route down Lac Champlain they have the gunboats to make it work this time.
There's a good railway/roadway from St Johns to Portland. The US rail has to take a rather convoluted route to get to Portland (up to Burlington, which is threated by the British advance on Ft Montgomery, down to Boston and then up the coast).
Without domination of Lake Ontario (which I assume the British have), and occupation of Sackett's, if the British advance too far down the Hudson they'd risk a force moving to Ogdensburg to threaten their LoCs. For anything more than a spoiling attack into Plattsburg, Sackett's needs to go first.
In the NE theatre, the key would seem to be the Connecticut River. It's a wide, defensible river (from either side), and the first geographic anchor the British would meet.
Union armies? Grant(or DCB I suppose) must break through to New Orleans and the Union must hold the Tennesse behind him. I see some potential for a big battle here maybe Shilo maybe something else.
We're asking him to do more, with less resources (I assume some troops and supplies will be stripped to go north) against better opposition (more troops and better equipped). Halleck's Army Group isn't going to get to NO.
In the East the Confederates advance the Union defends who knows what happens but in my scenario above the Union holds and nothing much changes.
Fair enough.
Expect USN to send its big fast merchant cruisers to raid, no privateers no one is that daft. Vanderbildt, Keystone State etc.. Expect one of them to raid a British port, Queenstown (Cork) for example.
Ah, be interesting to see her tackle the Guardship (a razee Liner) and the Fortifications:
