PREFACE.
to cause letters to be written to the Ordnance, to the Admiralty,
and other departments, with a view to their hearty furtherance
of the objects.
The Author was allowed to select from the Koyal Artillery
and Royal Sappers and Miners certain workmen, particularly
smiths and millwrights, in all twenty-seven, who were after
wards employed in Mr. Laird's yard in riveting, and in other
work connected with iron vessels. This measure was scarcely
of less consequence than the selection of officers. The qualifi

drawing, had particular reference to the wants of the service,
and when the selection was made, their names were submitted
to the King.
When the vessels, with their engines, and the other prepara
tions at Liverpool were well advanced, the following instructions
were issued for the guidance of the Expedition:—
COPIES OF INSTRUCTIONS TO COLONEL CHESNEY, THE OFFICER COMMANDING
THE EUPHRATES EXPEDITION.
No. 1.
Letter from the Duke of Wellington to the President of the Board of Control.
Foreign Office, November 28, 1834.

Colonel, on a particular service, to be Commander of the Expedition
about to be undertaken for the establishment of a communication between
the Mediterranean Sea and His Majesty's possessions in the East Indies,
by means of a steam communication of the river Euphrates, in confor
mity with the recommendation of the Committee of the House of
Commons to that effect.
I am at the same time commanded by the King to signify to you His
Majesty's pleasure that an instruction to the following effect be addressed
to Colonel Chesney:—
As the object of the House of Commons in appropriating a large sum
of money to be employed by His Majesty for the purposes of this expe
dition was the promotion of the commerce and general interests of His
