It was in part to escape from the unhappy environment of Somersby rectory that Alfred began writing poetry long before he was sent to school, as did most of his talented brothers and sisters. All his life he used writing as a way of taking his mind from his troubles. One peculiar aspect of his method of composition was set, too, while he was still a boy: he would make up phrases or discrete lines as he walked, and store them in his memory until he had a proper setting for them.

His departure in 1827 to join his elder brothers at Trinity College, Cambridge, was due more to a desire to escape from Somersby than to a desire to undertake serious academic work. At Trinity he was living for the first time among young men of his own age who knew little of the problems that had beset him for so long; he was delighted to make new friends; he was extraordinarily handsome, intelligent, humorous, and gifted at impersonation; and soon he was at the center of an admiring group of young men interested in poetry and conversation. It was probably the happiest period of his life.

It also brought Tennyson into contact with the Trinity undergraduate usually regarded as the most brilliant man of his Cambridge generation, Arthur Henry Hallam. This was the beginning of four years of warm friendship between the two men, in some ways the most intense emotional experience of Tennyson’s life. Despite the too knowing skepticism of the twentieth century about such matters, it is almost certain that there was nothing homosexual about the friendship: definitely not on a conscious level and probably not on any other.

The combination of the deaths of his father and his best friend, (Arthur Hallam having died suddenly of apoplexy), the brutal reviews of his poems, his conviction that both he and his family were in desperate poverty, his feelings of isolation in the depths of the country, and his ill-concealed fears that he might become a victim of epilepsy, madness, alcohol, and drugs, as others in his family had, or even that he might die like Hallam, was more than enough to upset the always fragile balance of Tennyson’s emotions. "I suffered what seemed to me to shatter all my life so that I desired to die rather than to live," he said of that period. For a time he determined to leave England, and for ten years he refused to have any of his poetry published, since he was convinced that the world had no place for it.

Although he was adamant about not having it published, Tennyson continued to write poetry; and he did so even more single-mindedly than before. Hallam’s death nearly crushed him, but it also provided the stimulus for a great outburst of some of the finest poems he ever wrote, many of them connected overtly or implicitly with the loss of his friend. "Ulysses," "Morte d’Arthur," "Tithonus," "Tiresias," "Break, break, break," and "Oh! that ‘twere possible" all owe their inception to the passion of grief he felt but carefully hid from his intimates. Most important was the group of random individual poems he began writing about Hallam’s death and his own feeling of loneliness in the universe as a result of it; the first of these "elegies," written in four-line stanzas of iambic tetrameter, was begun within two or three days of his hearing the news of Hallam’s death. He continued to write them for seventeen years before collecting them to form what is perhaps the greatest of Victorian poems, In Memoriam (1850).

Wordsworth, who had been poet laureate for seven years, had died in the spring of 1850. By the time Tennyson returned from his honeymoon, it must have seemed to many a foregone conclusion that he would be nominated as Wordsworth’s successor. Tennyson knew that the prince consort, who advised the queen on such matters, was an admirer of his, and the night before receiving the letter offering the post, he dreamed that the prince kissed him on the cheek, and that he responded, "Very kind but very German."

At the end of November 1853 Alfred and Emily Tennyson moved into the secluded big house on the Isle of Wight known as Farringford, which has ever since been associated with his name. Emily loved the remoteness and the fact that their clocks were not even synchronized with those elsewhere, but her husband sometimes had a recurrence of his old longing to be rattling around London. Most of the time, however, he was content to walk on the great chalk cliffs overlooking the sea, composing his poems as he tramped, their rhythm often deriving from his heavy tread.

It was perhaps his very isolation that made him so interested in the Crimean War, for he read the newspapers voraciously in order to keep current with world affairs. "The Charge of the Light Brigade" was one result in 1854 of his fascination with the heroism of that unpopular war.

Popularity of the kind he had earned had its innate disadvantages, and Tennyson was beginning to discover them as he was followed in the streets of London by admirers; at Farringford he complained of the total lack of privacy when the park walls were lined with craning tourists who sometimes even came up to the house and peered into the windows to watch the family at their meals.

In the years between 1874 and 1882 Tennyson made yet another attempt to widen his poetic horizons. As the premier poet of England, he had been compared—probably inevitably—to Shakespeare, and he determined to write for the stage as his great predecessor had done. At the age of sixty-five he wrote his first play as a kind of continuation of Shakespeare’s historical dramas. Queen Mary (1875) was produced in 1876 by Henry Irving, the foremost actor on the English stage; Irving himself played the main male role.

The climax of public recognition of Tennyson’s achievement came in 1883 when Gladstone offered him a peerage. The rest of his life was spent in the glow of love that the public occasionally gives to a distinguished man who has reached a great age. Many of the finest poems of his old age were written in memory of his friends as they died off, leaving him increasingly alone.

On 6 October 1892, an hour or so after midnight, he died at Aldworth with the moon streaming in at the window overlooking the Sussex Weald, his finger holding open a volume of Shakespeare, his family surrounding the bed. A week later he was buried in the Poets’ Corner of Westminster Abbey, near the graves of Browning and Chaucer. To most of England it seemed as if an era in poetry had passed, a divide as great as that a decade later when Queen Victoria died.
