The French and German Armies at the 2nd battle of Orleans

[Vanguard45]

For a story I'm writing , I am looking at the France Prussian War. Specifically the 2nd Battle of Orleans.
The wikipedia article is scant on information about the strength, movements, and weapons of the battle.
Could someone point me to some good sources

I found Moltke's recounting of the war, with a bit on that battle on page 224: https://www.gutenberg.org/files/36209/36209-h/36209-h.htm#Page_224
