The Trouble With Tercios

… and other pike and shot formations
As we get down to the meat of the Wars of Religion list book I realise we know need to make sure we’ve got the BG size for various formations nailed down so that we have a logical and consistent approach. Charles obviously had some ideas when he started on the rules and drafted out the “quick and dirty” beta lists, however, we must now IMO review these otherwise it will be too late, especially if anything needs to go into the rules.
I’ve started by looking at Tercios – and have been heavily influenced by this website in what I’ve written below http://usuarios.lycos.es/ao1617/home.html
Originally the tercios were c. 3000 men strong and were as much an administrative organisation as a tactical one. At times they exceeded this establishment figure and at other times fell below it.
For example when they first marched to Flanders (1571) we have Alba’s tercios with strengths of 2204, 3194, 1641 and 1757 men and the tercios which invaded France in 1596 were roughly 1600, 1400, 800 and 600 men.
Additionally it was possible for only part of a Tercio to be deployed.
Originally the Tercio was roughly 1:1 pike to shot, however, the amount of shot increased over time and figures for 1596 and 1601 show the Flanders army had roughly 2:1 shot to pike. The shot at the time was itself roughly 1:1 arquebus to muskets with the number of the latter increasing over time.
In 1632 the tercios were reformed. Although still theoretically 3000 men strong the reality was much different with the tercios at Nordlingen around half this size. By the second half of the C17th units were, in reality, about the same size as other European “battalion” units i.e. c. 600 men strong.
Nest part is looking at the battlefield formations.
The original formation is the classic massive pike block surrounded by shot with the majority massed at the 4 corners. Pikes are drawn up in the region of 25-30 ranks deep.
There are 2 alternative formations which appear to be for formations that are roughly half the size of a full Tercio. There is El Prolongado de Gran Frente where the pikemen are more like 16 men deep but maintain the normal frontage, and also El Gente which has the pikes in the normal depth but half the frontage. Both of these have shot in the usual proportions and still mainly massed at the corners of the pikes.
The “classic” style and the 2 variations are clearly all round formations.
By the C17th the El Prolongado formation now has the pikes roughly 10 deep with 2 shot sleeves and may well have essentially been just a large version of what was to become the normal European pike and shot formations. By comparison the Dutch also used 10 deep formations up smaller in overall size.
This is no longer an all round formation IMO.
By Rocroi in 1643 the tercios are described as “squadrons”, again like other European formations were along with “battalion”, and in Portugal formation depth of 6 ranks is recorded, once again like the usual European pattern. Writing around this time Montecuccoli suggests that the Spanish form up 7 deep.
Spanish formations are no longer different from everyone else.
For comparison other European pike and shot formations were:
Dutch – 10 ranks deep but the individual units (hopen) were 5/600 men strong; regiments were theoretically larger but were divided into hopen in the field; some hopen were created from sub-strength units. Hopen were effectively brigaded together in pairs or threes; brigades could be deployed in depth with hopen in each line the infantry were deployed in.
Swedish – 6 ranks deep; brigades were around 1200-1500 men, although some could be nearer 2000 men on occasion; brigades are formed by combining regiments as necessary.
Imperials – Wallenstein formed his troops up 7 deep in the 1630s; pike and shot bodies were around 1000 men strong formed by combining units if necessary.
ECW – Royalists copied contemporary European practice and formed up 6 deep from the start; Parliamentarians probably began 8-10 deep in imitation of the Dutch but the almost certainly dropped to 6 deep which was certainly used by the New Model; Scots presumably followed Swedish practice and were 6 deep as so many officers had served with the Swedes. Bodies of around 500 men were formed from regiments and brigaded together for deployment with brigades being in the region of 1000 – 1500 men.
So taking this all into account do we have the formations right in the lists (and rules) at present?
Thoughts and suggestions?
