Instructions to the fleet for The joint
army and navy battle operations
against surrendered German war craft
and the obsolete battleship Iowa off
the Virginia capes, from June 81 to
July 20, made public to-day, reveal an
elaborate program of mimic warfare.
The enemy vessels to be destroyed
U-117, U-l40, U-111 and U48, the
destroers G-102, S-132 and V-43, the
cruiser Frankfurt and the battleship
Ostefricsland
The former German craft will be
brought to the firing point and an
chored in position about fifty miles
east of Cape Charles light vessel in
not less than fifty fathoms of water.
If more than one ship of a type to be
bombed is in the same vicinity, the sub
marine or destroyer to be bombed will
be distinguished by red, white and blue
circles on the deck to avoid confusion.
Planes to Bomb U Boat
Opening operations against the u
1T will be launched by seven divisions
of naval planes, using 63-pound
bombs. If this submarine has not been
sunk by naval aircraft army planes
will attack with 250-pound bombs.
Should the aircraft fail to sink the
other submarines division Of destroy
ers will attack by guntire
Attacks by all aircraft will be made
at an altitude of not less than 1000
1eet and at maximum speed
The submarines will be anchored in
column formation 800 yards apart. The
destroyers, one for each submarine,
Will then approach from distance of
50O0 yards and attack, opening fire at
not less than 5000 yards. Each de-
stroyer will be allowed ten rounds a
gun.
At the conclusion of the gunfre anv
submarine afoat will be sunk by depth
charges by a wrecking party from the
North Dakota
The search for the Iowa will bring
into play all the ingenuity of aircraft
and destroyers. She will move ulaler
radio control of the Ohio, and at the
zero hour will be at some point be-
tween the latitude of Cape Hatteras
and Cape Henlopen, fifty to one hun
dred miles off shore, steaming at maxi
mum speed IN a general direction of
the shore. The Ohio, while controlling
the Iowa, will be five miles astern Of
her.
Army and navy seaplancs and foul
army dlrlglbles Will form a scouting
line between Cape Hatteras and Cape
Henlopen and will scout eastward for
one hundred miles off shore or until
contact is made with the Iowa.
Drive to Sink Iowa
As soon as contact is made aircraft
Will flash the news giving position,
course and speed of "the enemy"
Planes on the scouting line will then
assemble by divisions and proceed to
the attack in order Of light bomba rd :
ment squadrons, then heavy lombard =
ment squadrons and seaplanes.
The air attack on the Frankfurt will
be with navy 25O-pound bombs and
army 30o-pound bombs. The board of
observers will make an examination of
the ship after each attack A second
series of attacks will be made with
520-pound bombs.
The experiments with the battleship
Osttriesland on July 20, include a
series of aerial attacks, each plane
dropping two bombs in each attack. On
the second day 1,000-pound bombs will
be used and if a hit is scored 1000
pound bombs will be dropped.
Ii the bomb attack fails to sink the
Ostfriesland, the dreadnought Penn
sylvania will open fire with her main
battery at 10000 yards. If the Ostfries
land is still ahoat after the Pennsyl-
vania has used her heavy artillery, she
Will be sunk by depth charges.
