Label/Document Translation:

"Much vigilance against the 'fifth column,' against supports of Papal bulls, deviants, spies, traitors, and friends of pacts and compromises: which know and see that the city is not demoralized by their lies, which is disposed to conquer or to be conquered; We must pursue them until they are made to be silent. The difficulties will be great, but the triumph will be for the country. We can be optimists, but we have to be vigilant, very vigilant!!"
