Civil War Strategy and Tactics, pt. 4
May 13th, 2010 at 7:36 am (General, In the beginning...)
Infantry tactics are living ideas in times of warfare. In previous posts it has been suggested that linear warfare was the main type of warfare engaged in by the combatants during the Civil War. This should be understood nominally. In other terms, if a person considers all the land engagements that occurred during the Civil War, linear warfare will be the most prevalent tactical consideration in a general sense. Many general officers went into combat planning to use linear warfare for either attack or defense. In battle, however, it is common for plans to go awry suddenly and easily. As a result linear warfare tactics may have been the intent at the beginning but circumstance either caused or otherwise necessitated a change mid-battle. Similarly a different tactical plan might give way to linear warfare as when retreating troops were rallied to prevent a rout and possible reverse the fights fortunes.
The two major works on infantry tactics used by many commanders during the Civil War were Hardee’s Rifle and Light Infantry Tactics and later Casey’s Infantry Tactics. For these books and others in their full length, click here. Hardee and Casey both represent general ideas about moving men around on the field. As previously indicated tactics generally meant putting men in a formation that would allow them to effectively attack or repulse the enemy. To this end neither Hardee nor Casey, at least in their works on tactics spent much time explaining when and why to use a particular tactic, but focused mostly on the how. To that end it is useful to explain the general construction and some important terminology associated with a Civil War era army.
In general (and it is important to remember that virtually nothing remains constant in combat) men were divided into companies. A company was lead by a captain and had usually about 100 men divided into 2 platoons. Each platoon had 2 sections and each section had 2 squads. Some quick math reveals that a platoon had about 50 men, a section about 25, and a squad about 12. A company usually had one captain, one 1st lieutenant, one 2nd lieutenant, one 1st sergeant, four sergeants and eight corporals. To save wordy descriptions a number of links are available to more thorough explanations as well as graphics.
The School of the Soldier is an excellent site. It uses simple flash animation to show many of the maneuvers described in Hardee’s Tactics.
Formations and Ranks in Civil War Units contains a discussion of the various organizational principles, which have been distilled below.
A regiment was composed of 10 companies. Some new northern regiments were made of two battalions of 8 regiments each. A regiment was lead by a colonel and battalions, if they existed, were lead by lieutenant colonels. Additionally a regiment had (in order of rank) a major, two surgeons (a major and a captain), an adjutant (1st lieutenant), a quartermaster and commissary (both lieutenants), a sergeant-major and quartermaster sergeant. A regiment also had a color guard that would carry the regimental colors (the flag specific to that regiment.)
A brigade was composed of 3 to 6 regiments. Brigades were lead by brigadier generals. A division was made of 2 to 6 brigades and was lead by a major general. At the beginning of the war the corps system had yet to be introduced. When it became apparent the war would not be the 90 day affair many people thought it would be, brigades were combined into corps. Corps were organized under major generals in the north and lieutenant generals in the south. Each corps usually had between 2 and 4 brigades. Finally, corps were organized into armies. An army generally encompassed a geographical theater of operation. Thus some army names during the Civil War were the Army of Northern Virginia, the Army of the Potomac, the Army of the Cumberland, and the Army of Shenandoah. Again, the north put major generals at the head of armies while the south used the simple designation general.
When on the march or in the battlefield (again, in general) the various units were organized into ranks and files. Based on the direction the unit was facing, the rank was the horizontal line of men while the file was the vertical line of men. Additionally when face to face with a unit of men in formation, the distance they covered from left to right was known as the company’s frontage.
A company had a number of maneuvers it might execute during a march, or in battle, but there were two final configurations in which the men commonly ended a maneuver. The first was to maneuver into a column. In column of fours the company’s frontage was four men wide, each man standing close enough to the next man to easily touch him. Thus the company had four files but a variable number of ranks depending on the current size of the company. This was the common formation for march from location to location. Other columns such as column of companies also existed depending on what was necessary for a particular situation. The second configuration was to maneuver into a line. In this configuration the men formed a line of two ranks. The frontage was the length of half the company with half as many files as there were men. This was the common configuration when going into battle. Both these formations could be extended into something the size of regiment, though on occasion the better part of a whole army would be in a single line or column.
At a tactical level the general officers would order some portion of their command to do something. The most common orders would be to attack some point, defend some point or feint toward some point. At this point colonels and captains did most of the work. They ordered their men forward, moved into columns to take advantage of road or moved into a line of battle in front of an enemy position, gave the order to charge, lie down, fire or attack with the bayonet.
These were the basic tactical considerations and they were taught by drill and practiced on the parade ground. Though simple, the goal was to get men to act quickly without thinking too much about the activity. As previously stated these were the maneuvers the men used but how, why and when to use a maneuver was something a bit more complex. In further posts I will attempt to explain these considerations based on events that may have transpired during a battle.
