Caswall was educated at Marlborough Grammar School and Brasenose College, Oxford, where he graduated Bachelor of Arts in 1836 with honours and later proceeded to Master of Arts. He was curate of Stratford-sub-Castle, near Salisbury, 1840–1847. In 1850, his wife having died the previous year, he joined the Oratory of St. Philip Neri under future Cardinal Newman, to whose influence his conversion to Roman Catholicism was due.
He wrote original poems that have survived mainly in Catholic hymnals due to a clear adherence to Catholic doctrine. Caswall is best known for his translations from the Roman Breviary and other Latin sources, which are marked by faithfulness to the original and purity of rhythm. They were published in Lyra Catholica, containing all the breviary and missal hymns (London, 1849); The Masque of Mary (1858); and A May Pageant and other poems (1865). Hymns and Poems (1873) are the three books combined, with many of the hymns rewritten or revised. Some of his translations are used in the Hymns Ancient and Modern. His widely used hymn texts and translations include "Alleluia! Alleluia! Let the Holy Anthem Rise"; "Come, Holy Ghost"; "Jesus, the Very Thought of Thee"; "When Morning Gilds the Skies"; and "Ye Sons and Daughters of the Lord".
