Thank-you very much! The map found in the OR Vol XXXIV part 1 pp 234-5 and directions for reading the map were extremely helpful! If you can remember the name of the person who made the other maps, or any additional information, it would also be much appreciated. I am still researching the book on Likens' 35th Texas Cavalry and have an account as well as casualties at Mansura. Apparently some of Likens' and Terrell's men were deployed as skirmishers to protect the artillery.

Sincerely,
William Bozic
