 Lumsden also encouraged Brigade members to be blood donors and advertised in the Irish national papers for people to register to set up an 'on-call' blood donor panel to serve hospitals in the Dublin area.The service later became the National Blood Transfusion Association in 1948 but owes its origin to the Brigade and more especially to Sir John Lumsden.In 1922 the Irish Civil War caused the Brigade to go into the front line to help both sides.
