Hello Nigel, interesting video but slightly off factually. The Black and Tans and the Auxiliaries were separate organisations. the Tans (the R.I.C. Special Reserve) numbered 9,500, far from professional and not very effective. However the Auxies (the Auxiliary Division of the R.I.C.) numbering 1,900 were effective mostly because they were well trained and professional in that they were all former British Army officers. They were also paid a lot more than the Tans for the same reason. It's a part of Irish history that's not taught very well in schools here. hence the confusion at times.
