Manus O'Cahan's Regiment of Foote is Irish in origin and fought predominantly in Scotland during the English Civil War.  However, like the Scots Brigade itself, you do not have to be Irish to join our ranks.

As an Irish regiment however (alongside Laghtnan's), we do differ  from our Scot's counterparts of Gordon's and Frasers in terms of our history and how we came to become embroiled in the English Civil War - more information on this can be found in the O'Cahan's History section below.

Traditionally within the Sealed Knot, O'Cahans has been the more pike-dominated regiment of all the Scots Brigade however we also have members fulfilling other roles too and we have a good mix of male and female members.



Our members have a wide range of interests outside of the Sealed Knot from roller-skating to biking to sewing and reading so we're quite an eclectic lot.

Many of us have been camping and fighting alongside each other for decades now - some even having been born into the Knot and now continuing as adult members alongside the original parents.

It is true that a great many of us are based in Scotland so we often have the furthest to travel to attend musters and banquets but let us reassure you, it is so worth the extra effort.





  • A green field with a red Irish Cross.

  • The letters C and R are also in red.

  • The Imperial crown and the legend ‘VIVAT REX CAROLUS’ are to be in gold.

This is the most important colour in the Regiment, being that of the Colonel’s (ie, No.1) Company.  This colour shows clearly the Regiment’s Irish origins, as well as paying tacit acknowledgement to their Royalist allegiances. It is a literal copy of one of the known Irish Confederation Flag designs.

O'Cahans men

Olive green doublet with olive green or russet breeches.  Headgear is Monmouth-style caps when portraying the Irish or a blue bonnet when acting out a Scots part.

O'Cahans women

Standard women's kit.   Colours are not restricted but often women will adopt the Regiment colours.  An apron and modesty decolletage linen may also be worn.  Heads are usually covered unless unmarried.


  • A rich blue background (similar to a Prussian Blue), with a gold sunburst.

  • The Madonna will be a traditional dark haired figure dressed in lighter blue. She will be standing on a silver crescent amongst white clouds, and be crushing the serpent’s head beneath her feet.

  • The legend ‘SIC PEREANT HAERESES’ translates (roughly) as ‘In this way heresy perishes’.


This is the Lt. Colonel’s (ie, No.2) Company colour, and  is a splendid design from the same source as the Col’s colour and we will find the excuse to fly it when we want to.


Manus O'Cahan was a real-life historical figure.  Of Northern Irish origin and staunchly Catholic, Manus O'Cahan learnt his military prowess in the 30 Years War and Irish Rebellion. Manus O'Cahan's regiment later formed part of the army of the Marquis of Montrose who fought for King Charles in Scotland against the Army of the Covenant; one of three Irish regiments to fight on the mainland in what is generally known as The English Civil War but did in fact eventually involve all three kingdoms.


To be Irish at this time was considered less than human and there are frightful tales regarding the Irish and how they were treated.  O'Cahan's Regiment fought many a battle alongside Laghtnan's Regiment of Foote and other Scots before their wicked slaughter at the battle of Philiphaugh in the Scots Borders in 1645.
