to duty, his eyesight fully restoreil. In 1^43 he
sailed to the Mediterranean on the frigate Cum-
berland, returning late in 184.J by reason of the
threatened war with Mexico. He was assigned
tu ordnance duty at "Washington in 1847, much
against his wish, as his inclination was for active
service afloat. His progress and promotion was
rapid and he introduced imijrovements and
innovations that made the ordnance department
of the U.S. navy the most etiicient and formid-
able in the world, and this in spite of determined
opposition from the t)lder ordnance officers. He
continued in the department for sixteen years,
reaching the position of chief of ordnance. The
Dahlgi-en shell gun and its accessories was the
crowning result of his inventions, and when in
1861 the civil war put it to the severest tests it
proved the wisdom and forethought of its inventor
and projector. He instituted the foundry for
cannon, the gun-carriage ship, and the experi-
mental battery. He was made commander in
is,").j, and in order to test his apparent innovations,
he was allowed to equip the sloop-of-war I'lymouth
with his XI. -inch guns and other modern ord-
nance considered too heavy for sea service. In
1857 he visited the European coast from Portu-
gal to Holland, and in 1858-59 cruised in the
AVest Indies, testing the gun's efficiency and
adaptability to naval warfare. In the civil war
liis guns and heavy ammunition quieted the
Merrimar in Hampton Roads, opened the Missis-
sippi at New Orleans and Vicksburg, gave Port
Royal to the Union forces as a naval station,
sealed Charleston, Wilmington and Savannah to
blockade runners, captured Mobile, and sunk the
Alabama. In 1861 Commander Dahlgren was at
the Washington navy yard and because of
the disaffection in the navy, he was the senior
officer left in that yard loyal to the government.
He held the yard for four dajs, until Federal
troops relieved him. He was promoted captain
in July, 1861, remaining commander of the yard.
In July, 1862, he was made chief of the Bureau
of ordnance, and in February, 1863, he received
from congress a vote of thanks and was made rear-
admiral. In July, 1863, he succeeded to the
command of the South Atlantic blockading
sfjuadron whicii comprised ninety vessels of war
including the iron-clad monitor fleet at Charles-
ton, and guarded three hundred miles of coa.st
and twenty-five ports. He succeeded in silencing
Fort Sumter and the batteries on Morris Island,
put a stop to blockade running, led a successful
exf>edition on the St. John's river, co-operated
with Sherman in the capture of Savannah and
entered Cliarleston in February, 186.">. He com-
manded the South Pacific sf|uadron in 1866 and
was again chief of ordnance, 1800-70, being
relieved at his own request and appointed to the
command of the Washington navy yard. He
was married after lie returned to Washington, in
1865, to Mrs. Madeleine Vinton Goddard, only
daughter of the Hon. S. F. Vinton, representative
in congress from Ohio. His published works
include: 32 pdr. Practice for liamjcrs (1848); Exer-
cise and Jlanceuver for the Boat lloicitzer (1852);
Boat Armament (1852. 2d ed., 1856); Fercnssion
System (1853); Ordnance Memoranda (1853); Shells-
and Shell-ffuns (1856); and Memoir of Ulric
Dahhjren (1872); besides numerous reports,
memoranda and notes on ordnance published in
pamphlet. He died suddenlj- in Washington,
D.C., July 12, 1870, and was buried in the family
burying groimd at Laurel Ilill, Philadelphia.
