Gaines Landing is shown on OR Atlas Plate 47-1 on the Mississippi River, approximately 25 miles south of Napoleon. About 8 miles NE of Lake Village & 3 miles South of present day Dewey on State/County Road 159. The road from Gaines Landing to Monticello passed through Bartholomew and Bowden, Plate 154, G-6,
Four miles East of Monticello, there was cut-off to Rough & Ready 4 miles SW.

GENERAL ORDERS No. 52.

HEADQUARTERS CHURCHILL'S DIVISION,
Monticello, September 25, 1864.

I. The major-general commanding district will review the troops to-morrow at 2 o'clock precisely, on the parade ground selected, on the Gaines' Landing road. The brigade commanders of this division will report at these headquarters this evening at 5 o'clock for further instructions.

By command of Major-General Churchill:

B. S. JOHNSON,
Major and Assistant Adjutant-General.
OR V41 Pt. 3, p. 957

I'd believe this road would be the present day State or County road 35 to Collins, possibly the Bartholomew of old. The reviewing site couldn't have been too far out of Monticello.
