Not only had he already a subaqueous conductor, but he invented an ingenious, though simple way of igniting the powder by means of pieces of charcoal, shaped in such a manner that they did not fail to produce the effect. In the autumn of 1812 he actually exploded powder-mines across the river Neva, near St. Petersburg.

In one of Soemmerring’s later letters to Baron Schilling, he, alluding to his subaqueous conductor, says that the means found out by him (Schilling) to ignite, by the galvanic current, gunpowder at a distance (das Fernzünden)
