German invasion of the Netherlands
As antitank-guns 386 Böhler 47 mm L/39s were available, but there were not enough. There were another three hundred old  6 Veld (57 mm) and 8 Staal (84 mm) field guns. Only eight of the 120 modern 105 mm pieces ordered from Germany had been delivered at the time of the invasion. Most artillery was horse-drawn.
