Okay, so I just won my first full campaign as the South. My settings were normal difficulty, full AI behavior, normal aggressiveness, and everything else pretty much set to normal, and the setting that slightly improves the AI but increases turn time.
It is early June '64. I'd had General Lee, along with another powerful corp. sitting across the river from D.C. for well over two years. Primarily, it was to keep the large union force protecting D.C. from ever leaving, while I wrecked havoc on their flanks.
Over the past two years most of the war had been fought in Tennessee, Kentucky, and Missouri. For those two years, I had slowly and steadily gained ground, conquering all of those three states. I used constant cavalry raids north of West Virginia to tear up tracks and blow depots. I also controlled several towns in Indiana and Illinois.
Back to the east. I had made two attacks, one a year, in an attempt to draw out the union forces (like Lee did leading up to Gettysburg). Each time I was overwhelmed by superior Union numbers. Even when battles when 2-1 in my favor, their numbers would still wear me down.
So, I settled back, built forts along the James(?) river and let them pound against my level 8 fortifications. Eventually come '63, I marshalled two strong corps of 30k men each, and a cavalry force lead by Stuart and others of about 20k. They struck north of D.C. capturing several cities, 4-6 regions north of D.C. Winter that year was long and harsh, so had the two corps hole up in a city, thinking they would just pass the winter there, north of D.C., but well within striking range when the weather warmed. Well, in late Feb., eight, yes eight Union corp attacked and besieged my two corp. It must have been 100k-150k men. I tried to send reinforcements without weakening my line too much, but they were beaten back. I couldn't get any supplies through. After 2-3 months, they surrendered. I was stunned. I couldn't believe it. More than a third of army in the area had been wiped out.
After I wiped away the tears, knowing the hell my men would go through in a Union POW camp, I let my cursor stroll over D.C. in seemingly impotent rage. And low and behold, a miracle! D.C. was protected by a measingly 3 Corp. or so. I immediately send Lee and other corp in a mad rampage across the river. It was do or die. I had massive batteries of siege artillery, 20 lbers., and Parrot rifled cannon. At sea, I had 6 ironclads firing in support. I pressed, "end turn" with great trepidation.
Turn Processing . . .
Supply 1, 2, 3, 4, 5, 6
Day 1/15 . . .
On day twelve, hell froze over. Lee and his men smashed into D.C. with fury. They fought through the alleys and streets. Onward! To Victory! The artillery boomed in support. The roads out of D.C. clogged with the mass of refuges fleeing my army. The Union reinforcements couldn't make it in time. By the end of the day, D.C. was mine. It cost 12 thousand causalties, but I took the city, and won the war. Decisive victory was mine.
I'd like to say sacrificing my two corp to draw away the enemy armies guarding D.C. was a tactical choice I made, but I can't. But, hey, isn't there something about snatching victory from the jaws of defeat . . .?
