The past progressive is most useful when

when an action happened in the past
when an action was uninterrupted in the past
when an uninterrupted action happens
when an action gets increasingly common

When an action gets increasingly common.

Explanation:

The past progressive verb form illustrates an action that was in continuity or progress in the past. It displays the several actions like actions of the past that were interrupted, the two actions happened simultaneously, an action taking place when another happened but it would best describe the action when it gets increasingly common. For example, "He was drafting a letter when I reached there" or 'They were cooking dinner and I was watching T.V. effortlessly'. These two statements best illustrate the increasingly ongoing actions of the past that are "writing", "cooking", "watching" which were in progression at that time.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
