Irish Militia:

Unit colours:

“Like the regular army each battalion followed a standard practice for colours. Each had a king's Colour that was a Union Flag, and a battalion colour which was the colour of their uniform facings with a Union Jack in the canton. However unlike the regulars their does not seem to have been a standard practice for the devices and insignia displayed on them or of the material they were made of or how they were made. Most seem to have displayed a royal cypher or battalion name rather than a number. We are fortunate in that the National Museum of Ireland has in its possession remnants of some Militia colours. These are mostly second generation flags presented after the 1801 Act of Union. We know they were not the first because their is a newspaper article that describes a Militia battalion being presented with new colours in Armagh:
"The regiment was drawn up in funeral procession before Major Cope's lodgings, commanding at Ennis at present. The ancient banners were given out, with which they proceed, the band playing solemn dirges, to the exercise ground. Here they formed a hollow square, in the centre of which the colours were burned and the ashes interred, over which the regiment fired three rounds. This ceremony concluded, the regiment again formed a hollow square and were presented with the new standards." ” : https://samsflags.blogspot.com/2014/12/development-history-of-irish-flags-pt8.html
