Custine. In the neighbouring fortress of Mainz, the key to Western Germany,
Custine's advance was watched by a republican party among the inhabitants,
from whom the French general learnt that he had only to appear before the
city to become its master. Brunswick had indeed apprehended the failure of
his invasion of France, but he had never given a thought to the defence of
Germany; and, although the King of Prussia had been warned of the
defenceless state of Mainz, no steps had been taken beyond the payment of a
sum of money for the repair of the fortifications, which money the
Archbishop expended in the purchase of a wood belonging to himself and the
erection of a timber patchwork. On news arriving of the capture of Spires,
the Archbishop fled, leaving the administration to the Dean, the
Chancellor, and the Commandant. The Chancellor made a speech, calling upon
his "beloved brethren" the citizens to defend themselves to the last
extremity, and daily announced the overthrow of Dumouriez and the
approaching entry of the Allies into Paris, until Custine's soldiers
actually came into sight. [21] Then a council of war declared the city to
be untenable; and before Custine had brought up a single siege-gun the
garrison capitulated, and the French were welcomed into Mainz by the
partisans of the Republic (Oct. 20). With the French arms came the French
organisation of liberty. A club was formed on the model of the Jacobin Club
of Paris; existing officers and distinctions of rank were abolished; and
although the mass of the inhabitants held aloof, a Republic was finally
proclaimed, and incorporated with the Republic of France.

The success of Custine's raid into Germany did not divert the Convention
from the design of attacking Austria in the Netherlands, which Dumouriez
