Yes.
3. Secondly, a military raid on Blyth for the purpose of destroying Elswick.
We have hitherto assumed 10,000 men for Blyth-Newcastle; either more or less may be required. The force must be numerous enough to make its way in the face of sporadic opposition by unmobilised territorials and by the population, from Blyth to Elswick; to seize and destroy effectively the Elswick Works and the ships in the Tyne. It seems improbable that less than 10,000 men would be sufficient.
Yes.
4. Thirdly, a raid of not less than 20,000 men on Harwich, with the object of stopping the regular army from going to France.
The Harwich operation is essentially—
(a.) The secret concentration and embarkation of 20,000 men.
(b.) The destruction of the floating and land defences of Harwich by the escorting hostile squadron.
(c.) The disembarkation of 20,000 men with a proportion of artillery before the British Fleet can arrive in sufficient force to give battle.
