PREFACE.
xi
Majesty's subjects, it will be Colonel Cliesney's first duty to use every
exertion to secure the success of the expedition in the shortest possible
time, and always to bear in mind the necessity of making his arrange
ments in such a manner as that their utility may be permanent in the
event of his success.
Colonel Chesney will further be careful to maintain the most perfect
discipline and subordination among the persons who compose the expe
dition. He will explain to them that His Majesty will view with the
severest displeasure any conduct on their part calculated to defeat the
objects of the expedition, whether arising from disagreement among
themselves, or from an indifference to the habits and prejudices of the
inhabitants of the country in which they are employed.
It will be the duty of Colonel Chesney, and of every other individual,
to conciliate to the utmost of his power the friendship and goodwill, not
only of the authorities of the Grrand Seignior, but of the different com
munities and tribes with whom he may have intercourse; to abstain from
all acts calculated to rouse the prejudices of the inhabitants; to take no
part in any disturbances or quarrels which may exist among adverse
tribes ; and to avoid all acts of violence, unless in the last extremity, for
the preservation of the lives of His Majesty's subjects.
In short. Colonel Chesney is always to bear in mind that the character
of the expedition is one of peace; that it is undertaken with the permis
sion of a friendly power, without whose countenance and co-operation
success cannot reasonably be expected; and that having for its object
peaceful and beneficial interests, it is only to be conducted by peaceful
means.
Colonel Chesney will find His Majesty's Ambassador at the Porte
instructed to afford him all possible assistance in the way of representa
tion to the Turkish government, on any occasion where the intervention
of that government with its authority is required. Colonel Chesney will
communicate with His Majesty's Ambassador on all such occasions, and
pay to his suggestions that attention which the position held by him at
the Porte entitles him to expect. _ > _ . „
Lastly, Colonel Chesney will report from time to time, for the infor
mation of His Majesty's Government, the progress and prospects of the
expedition.
I have, &c,,
