"The foreign invasion throws great masses of airplanes and artillery at our fronts. Let us construct fortifications and refuges which will protect the lives of our soldiers and on these [refuges] the teeth of facism will break. All able arms of combatants for fortification! Not one minute of rest! The moment demands the greatest sacrifices from us! Fortification! Fortification! Fortification!"
