Lines written by a Revolutionary Soldier.

On taking a retrospective view of my sufferings while in the Revolutionary army, in which I served three years and a half, in which time I suffered with hunger, cold, and want of clothing.

ON the cold earth I oft have lain,

Oppress'd with hunger toil and pain,

While storms and tempests roar'd around,

And frost and snow had cloth'd the ground

The British troops, did us assail,

In storms of snow, and rattling hail,

All this with patience long we bore,

Until that sanguine war was o'er,

And Independence made secure,

For which we did those toils endure,

Our hostile foes then left our shore,

Retired for to return no more,—

Fair freedom now her laurels spread

O'er hostile fields where warriors bled;

No more we hear the din of war,

Nor thund'ring cannon from a far,

Here peace spreads o'er our fertile plains,

No tyrants shake their galling chains,

Our ships safe o'er the ocean glide,

And waft in wealth with ev'ry tide,

My friends remember us who bled,

When on the sanguine fields you tread,

Nor spurn us if of you we crave,

Some aid while tot'ring oer the grave.

Our fleeting days will shortly end,

Then with our native dust we blend,

Death soon will close our languid eyes,

And all our cares beneath the skies:

Columbia's sons who us survive,

And in this land of freedom live,

Revere that Providential hand,

That long has blest your happy land—

Your Constitution ever prize,

Your tow'ring same will reach the skies,

And while you all in Union blend,

It will from war your shores defend—

Daily improvements here are made

For agriculture and for trade,

Here tow'ring manufactures rise

Where'er you turn your wandring eyes;

Your treasuries now with gold o'erflow,

Riches abound where'er you go,

No hostile banners you alarm,

You sit at home free from all harm—

Long may your happy land be blest,

And you enjoy both peace and rest;

Generations yet to come,

Shall find a lasting peaceful home.

Look back and see what we have done,

Extol the victories we have won,

And when we all in dust shall sleep,

To our memories will long vigils keep,

And o'er our heads will trophies raise,

With lasting songs of joy and praise.

And now my friends a long adieu,

Our fleeting days are short and few,

We soon must leave this trying shore.

And land where time shall be no more.

The correct option is B) suffering endured during the war.

Explanation:

We can reach the correct conclusion through elimination. The speaker of the poem was a Revolutionary soldier. He fought during the war for independence. Therefore, letter A is eliminated, since he is an American fighting the British. At no point does he show remorse for fighting a worthy enemy as letter C describes. It is quite the contrary: the speaker is proud of how his independent country has thrived after winning the war and sending away the enemy. He does not express sorrow over the loss of friends as well. The speaker does ask the new generation to not forget about him and the others who have fought for their country. He does not, however, show sadness for those who have died or for his own death, which he thinks is getting closer. We can, thus, eliminate letter D.

Letter B is the best option. The speaker talks of all the suffering he and other soldiers had to endure during the bloody war. As we can see here:

ON the cold earth I oft have lain,

Oppress'd with hunger toil and pain,

While storms and tempests roar'd around,

And frost and snow had cloth'd the ground

The British troops, did us assail,

In storms of snow, and rattling hail,

All this with patience long we bore,

Until that sanguine war was o'er,

And Independence made secure

War takes its toll on the soldiers, as we can see. They either kill or get killed, either by the enemy or by other painful causes - hunger, the cold, the snow, storms etc. The suffering is great. But, according to the speaker, it is worth suffering to see your great country thrive.
