The Jarama March has been set by AABI in Madrid. The announcement shows it as a four day event:
Thursday - a play by Charlie Nusser and reception.
Friday - Visit to Madrigueras
Saturday - The March at Jarama to the positions of February 1937
Sunday - A visit to Fuencarral Cemetery.
For those with little background on who the Mackenzie-Papineau battalion were, you might be interested in this series of newspaper articles from the Daily Clarion in Toronto in 1937. Ted Allan ("This Time a Better Earth) wrote these first hand reports from Spain.
