British Army Intelligence Section

Introduction from Chronology

Lieutenant-Colonel Walter C. Wilson appointed as Intelligence Officer for Dublin District (Division) of the British Army.  (McMahon says that a ‘Special Branch’ within the BA’s Dublin District had been operational from March.)

More Detail

With MI5 assistance, Wilson set up a school for spies at Hounslow outside London.  Recruits, mainly ex-BA officers, were trained before being sent to Dublin.  These men worked in civilian clothes and took a variety of jobs (usually ones that gave them a cover for moving around).  By June 1st, Wilson had 7 officers; 51 by July and 82 by August.  It peaked in November with 97 staff with 75 of them being operatives. Expenditure in the 1920-1921 financial year was £20,000.

Some of the operatives frequented the Cairo Café in Grafton St in Dublin and thus became known within some IRA circles as the Cairo Gang. Although part of Dublin District of the BA, they often worked independently. They took part in a number of illegal activities.  The BA record of the rebellion notes that they were “partly pure intelligence and partly executive”.  See Dec-1920/6 for their amalgamation with Winter operation.

Other division and brigade I.O.s appointed over the coming months.  (Overall BA Intelligence was commanded by Colonel Stephen Hill Dillion or Dillon located in Irish Command HQ in Parkgate St in Dublin.) 

Kautt gives a list intelligence officers assigned to Divisions and Brigades of the BA in Ireland during this period (but Wilson is not on the list).
