This is what the historical battle looked like
But I had underestimated the cool determination of Brig.Gen Palmer, who flung his brigade forward without hesitation and retook the redoubt.
Here a view of the fighting in the centre and across to the twin Kuhn houses and the railroad beyond.
As always in actions of this complex kind, the schedule of reinforcements was crucial to the action. It turned out that both Gen. Smith's rebel division and the Union 3rd division arrived at more or less the same time - but significantly later than historically. The Union artillery managed to get off a few desultory shots, but the upshot was that there was no fighting at all around Fair Oaks station itself or on the right flank, as the picture below of the end of the action shows. Brig-Gen Gorman was especially slow in advancing.
And here, the arrival of reinforcements from II Corps around Casey's redoubt, which remained in Union hands at the end of the battle.
