Salvo Points 
(Applicable only to forts commanding a narrow channel.) 
I.—When a ship advances to within 120Qyards (b) of the first “ salvo 
point** with the intention of “ running past/* the battery 
commander gives the signal: “ Lay on salvo points **—viz., 
“ Puts visual dials to zero ** or “ Electric dials to stops.** On 
this signal, G.G.C.*s order their groups to be laid on “ salvo 
points ** as under( c ) :— 
M Group on points, Nos.&. 
(b(^ Gronp on points, Nos.& 
/c\ Group on points, Nos.&. 
II.—After the dials have gone to zero for “ salvo points,** no notice^ 
is to be taken of any subsequent range appearing on the 
dials until the ship has either passed the last point or is dis¬ 
abled, when the order to “ concentrate ’’—vide III. below— 
will be given by the B.C. 
III.—If a ship is disabled when passing “ salvo points,** the B.C. 
gives the signal “ to concentrate ** by raising a “ blue flag ** 
at his fighting station and blowing a whistle to attract atten¬ 
tion. On this signal, all groups concentrate on the disabled 
ship at the mean range of the two “ salvo points,** between 
which she then is until the correct range appears on the 
B.C. dial. 
IV.—After a ship has passed “ salvo points,** groups will continue 
firing independent group salvos until “cease fire** or “ change 
of objective ** is sounded. 
V. —The ammunition for “ salvo points ** should be conspicuously 
painted and kept specially handy for loading, as, if it has to 
be carried any distance, some of the points will, assuredly, be 
missed. 
VI. —When the signal “lay on salvo points** is given, any gun 
which is just about to fire at a known range should deliver its 
fire before training on to “salvo points.’* 
a These are imaginary poinis in mid-channel over which the ship must pass and whose range 
and training have been previously determined and painted on the gun-drums.—“ Gr.A.D.” (1895), 
Vol. I., p. 486. 
b A ship steaming 14 knots will traverse this distance in just over two minutes. 
c The combination of salvo points must be arranged locally. 
d This is necessary to enable the B.C. to pick up the ship’s range again as she passes the fort, 
so as to have same (with all necessary corrections) on the dials the moment the vessel has passed 
the last salvo point.
