American military balloon unit inflating a reconnaissance balloon with hydrogen (1862). The balloons used were of varnished silk and, in spite of a small amount of leakage, they still retained sufficient gas to make ascents some days after their initial inflation. Engraving from 'Astra Castra' by Hatton Turnor (London, 1865).
