When twelve and fourteen find thirteen bearing from them, respectively, N.W. and N.E. (that is, at an angle of 45° with the course N.), they steam at full speed; eleven and fifteen steam at full speed, when twelve and fourteen bear from them, respectively, N.W. and N.E.; and so with the remaining vessels.

It is evident that the fleet may be formed into double echelon from the right centre vessel, or from the two centre vessels, according to the same principles.*

92. The fleet being in line, heading N., to form it into double echelons from the centre of divisions, preserving the original direction.

Suppose, for example, it be required to form each division into double echelon on its left centre

*Of course thirteen's pennant is hoisted above this signal. See Index of Signals.

The commander-in-chief makes signal :

From the left centre of divisions, form double echelon.*

Divisional commanders signal: Division-from the left centre vessel, form double echelon.

In each division the left centre vessel continues at full speed; the vessels on the right and left of her slow to steerage-way until she bears from them, respectively, N.W. and N.E., when they resume their speed.

It is evident that the fleet may be formed into double echelon from the right centre vessel, or from the two centre vessels of divisions, according to the same principles.

* In making this signal, the commander-in-chief runs up the distinguishing pennants of five, thirteen, and twentyone over number 69 (see Index of Signals), while each divisional commander hoists number 69 under the distinguishing pennant of the vessel of his division, which has been designated by the commander-in-chief.

93. The fleet being in line, heading N., to form it into double echelon from the flanks,* that is from the van and rear vessels (or vessels on the extreme right and left), preserving the original direction. Suppose, in this case, the commander-in-chief desires to form it from the flanks, on the left centre vessel.t

FIG. 121.

The commander-in-chief makes signal:

From the right and left of fleet-on the left centre vessel-form double echelon.

With the wings in advance, in other words.

If ordered to be formed on the right centre, the vessel on the extreme left would be the first to move forward; if on the two centre vessels, the vessels on the extreme right and left of the fleet would continue at full speed, as is evident.

The commander-in-chief here hoists thirteen's distinguishing pennant over number 70. (See Index of Signals.)

Which is repeated by the divisional commanders.

One continues onward at full speed; the other vessels slow to steerage-way. When two finds one bearing from her at an angle of 45° from the course (N.E. in this case), she hoists the position pennant as a signal to the vessel on the extreme left, and with this vessel resumes full speed; three and twenty-three steam at full speed when two and twenty-four bear N.E. and N.W. from them, respectively. The other vessels manœuvre in a similar manner; thirteen resuming full speed, when twelve and fourteen bear from her N.E. and N.W., respectively.

Double echelon may be formed from the flanks on the right centre vessel, or on the two centre vessels of the fleet, according to the same principles.

94. The fleet being in line, heading N., to form it into double echelons from the flanks of divisions, on their left centre vessels, preserving the original direction.

The commander-in-chief makes signal:

From the right and left of divisions on the left centre vessels-form double echelons.*

The divisional commanders signal: Division— from the right and left-on the left centre vessel form double echelon.*

The vessels on the right of divisions (one, nine, and seventeen) continue at full speed; the other vessels slow to steerage-way. When two, ten, and eighteen find one, nine, and seventeen bearing from them, respectively, at an angle of 45° with the course (N.E. in this case), they hoist } *The commander-in-chief here hoists the distinguishing pennants of five, thirteen, and twenty-one over number 70 (see Index of Signals), while each divisional commander hoists the same number under the distinguishing pennant of the vessel of his division designated by the commanderin-chief.
