Disguising a command.

(2) With the SECOND PERSON, will is used to express command. This puts the order more mildly, as if it were merely expected action; as,—

You will proceed to Manassas at as early a moment as practicable, and mark on the grounds the works, etc.—War Records.

Mere futurity.

(3) With both SECOND AND THIRD PERSONS, will and would are used to express simple futurity, action merely expected to occur; for example,—

All this will sound wild and chimerical.—Burke.
