Very little additional info then you've probably gathered off the internet but here is the text of correspondence from Commander Woodward noting the construction of kites for use at Vicksburg in 1863 - Maybe give you a couple names, dates and locations to use in your search.Report of Commander Woodworth, V. S. Navy, regarding the preparation of kites for use in the operations.
U. S. S. General Price,
Below Vicksburg, June 29, 1863.
Sir : Your communications and scraps were received this afternoon.
I have an expedient for getting them into Vickshurg, where they will be more sure of reaching the parties for whom they are intended than the shell.
I am having a number of kites made, and shall have them landed into Vicksburg to-night or to-morrow morning.
Please send me some more of the scraps.
Very respectfully, your obedient servant,
Selim E. Woodworth,
Commander, Commanding Price.
Acting Rear-Admiral David D. Porter.https://tinyurl.com/kkxywy5
