April 24th , 1913
The Larne gun-running was a major gun smuggling operation organised in April 1914 in Ireland by Major Frederick H. Crawford and Captain Wilfrid Spender for the Ulster Unionist Council to equip the Ulster Volunteer Force.
The operation involved the smuggling of almost 25,000 rifles and between 3 and 5 million rounds of ammunition from the German Empire, with the shipments landing in Larne, Donaghadee, and Bangor in the early hours between Friday 24 and Saturday 25 April 1914.
The Larne gun-running may have been the first time in history that motor-vehicles were used “on a large scale for a military-purpose, and with striking success”.
