Yes, many were the attempts to have arms and supplies ["stores"] crossed to Hindman and later to Holmes.

My singular point was in reference to artillery actually brought over by Parsons. And, from what I can piece together, it does not appear that any more than one 5 gun battery and a wagon train of stores accompanied Parsons.

Head Quarters Trans Miss District
Little Rock, Arks., July 6, 1862
I apply for two million dollars ($2,000,000.) to purchase Cotton, with which to buy arms & etc in Mexico: and have sent Rev. Ballard S. Dunn to get it, upon requisition approved by me.
It is necessary I should have arms, and ordnance stores to enable me to resist the heavy forces now in my district and threatening it. As yet, not a gun nor a pound of powder, a solitary cap nor anything else, has reached me from east of the Mississippi. As I have not failed to make frequent and urgent applications, I suppose the delay grows out of the scarcity there, or the difficulty of crossing the Mississippi, perhaps both.
Very Respectfully, T. C. Hindman

Head Quarters Trans Miss District
Little Rock, Arks., July 19, 1862
Major...I have gathered up, by purchase and impressments, about all the arms within my district. It is perfectly certain that not one thousand more guns more guns can be obtained. Of those that I have, only about 800 are valuable, balance being shotguns and common rifles.
In response to my previous appeal for arms, Gen. Beauregard ordered turned over to my Ordnance officer, Maj. Lockman some 450 damaged shot guns and rifles - and sent me a worthless battery - these I have received.
Curtis is devastating eastern Arkansas - a gunboat and transport fleet is at the mouth of the Arkansas River. A federal force of between 1,000 and 5,000 is in the Cherokee nation. Another federal column of about the same strength is in North West Arkansas.
If arms and ammunition were furnished me, I could do something in the way of defence - without them, I am nearly powerless.
There are old muskets and batteries in abundance east of the Mississippi: I apply for them - The requisitions I send do not cover the fourth of my wants. I have stated the facts. Begging and complaining cannot add to their strength.
Very Respectfully T. C. Hindman

May I ask that a copy of this be forwarded to the secretary of war immediately?

HEADQUARTERS ARMY SOUTHWEST, Helena, Ark., July 16, 1862. I am credibly informed that General Price has been crossing troops at Gaines Landing below. I hope it will be in your power to send gunboats down to interrupt such a movement. I also desire to move my command, partly on transports; and gunboats seem necessary as convoys on the Mississippi and White rivers. I have the honor to be, sir, very respectfully, your obedient servant, CURTIS, Major-General, U. S. Army. NAVAL COMMANDING OFFICER, Memphis.

HEADQUARTERS ARMY OF THE SOUTHWEST, Helena, Ark., July 20, 1862.
GENERAL: I have just returned from a reconnaissance down the river. A large amount of ammunition, small-arms, and some twenty-five pieces of artillery were crossed over into Arkansas last week near Gaines' Landing. The gunboats had passed to and fro while this was going on. I took and destroyed some 70 or 80 flat-boats, some of which had been in the business of crossing stores, and one small steamboat...

Gen Hindman to Brig-General John S. Roane Pine Bluff
Send an Officer to meet General {M. M.} Parsons of Missouri with this dispatch which he will receive as an order to him from General Hindman to have his command ...a suitable camping place near Arkansas Post and there report his strength, condition, etc. Wagons containing stores from [for] the army to move to Pine Bluff and the officer in charge to report their contents by telegraph.

8/5 Hindman to Gen Cooper-… The arms brought out by Capt Hart, together with those brought by Gen Parsons, have relieved me of embarrassment and enabled me to make effective the greater part of my command. If Major Bankhead arrives safely, as I think he will, I can then arm the balance of my men. I am waiting anxiously to hear of that officer's arrival on this side of the river.
I have six batteries containing forty brass pieces and one Btry of iron guns. I have a Co of Arty encamped near this place, to which I will give the 8-gun Btry coming in charge of Major Bankhead. By some blundering mistake a box of friction primes intended for me was left at Grenada. I have sent a courier to meet Major Bankhead, and if he has not a full supply of them the courier is to go on to Grenada to request Major Chambliss to send forward those left by Capt Hart.
If, therefore, Major Bankhead reaches me in due time, as, from your dispatch and Major Chambliss's letter, received by same courier, I am led to believe he will, I will have in a short time from 24,000 to 26,000 Inf, about 6,000 Cav, and fifty-four pieces of Arty near this place, to which I will give the 8-gun Btry coming in charge of Major Bankhead.
This letter was intercepted by Union forces. See Curtis to Halleck, August 15, 1862, p. 571.
