In a proclamation to the Irish people, de Valera urged them to show discipline and to be ready to resist should force be used….
Dublin greeted the Truce with joy.
Crowds flooded into the streets, and overladen trams took tens of thousands to the seaside. Members of the Auxiliary Division commandeered military vehicles to join them. Ice cream vans sold ‘Gaelic ice cream’, and the city’s dealers laid out the fruit and vegetable on their handcarts in patriotic displays.
from De Valera Rise 1882-1932 by David McCullagh (2017). Very Highly Recommended.
