A DECLARATION of the Officers and soldiers under the Command of colonel Twisleton, Governor of the Castle of Denbigh in Wales.  
KNowing the distempers that are already and the practices of our Enemies, both secret and open to distrube the peace of the kingdom, thereby to suppress the Authority of Parliament, and in it to invade and destroy all that is dear unto us, our Religion, laws, and Liberty, and instead thereof to bring a Tyranny under the pretence of the King's rights, and taking notice to the great grief of our hearts, how many Persons and Countries have been by their Insinuations and pretences drawn into a second engagement against the Parliament and their Army; We do therefore out of the sense of our duty to God, the kingdom and Parliament, unanimously declare as well for the satisfaction of each other, as others that are true friends to the Parliament and kingdom, that we will according to our national Oath and Covenant which we have Solemnly taken in our places and callings, and to the utmost of our power defend and maintain this Hold and Garrison of Denbigh and each other in pursuance thereof, under the command of the present governor colonel George Twisleton, against any power whatsoever that is not derived by Commission from his Excellency the Lord Fairfax and the Parliament to demand the same, and will neither for fear nor favour desert this our duty, nor in the discharge thereof desert nor forsake each other, in the performance of all mutual duties proper to our places, in which no extremity whatsoever by God's assistance shall make us unfaithful or inconstant in our resolutions or means to discover them, so to bring them to condign punishment, which baseness or Treachery we abhor the very thoughts of, and this Declaration as we make it freely from our hearts, so we as freely subscribe it under our hands.
