These weapons were relatively small, immobile, and fired large bolts or quarrels. Along with increases in the sizes of ordnance (the barrels) came the requirement of easier transportation. This led to two divergent approaches, the very light hand-gun, and eventually the arquebus, while another avenue of development led to the light ordnance, now on wheeled carriages, such as the 2-pounder Culvern moyane, the 1-pounder Falcon, and the 3/4-pounder Falconet. These lighter Renaissance pieces eventually led to the development of the 3-pounder and 4-pounder regimental guns of the 17th century as well as the leather cannon, notably in the army of Gustavus Adolphus.
