Within the framework of the construction of unitons via algebraic integration, using a twistor construction of \textit{N. J. Hitchin} [Commun. Math. Phys. 83, 579-602 (1982; Zbl 0502.58017)] and \textit{R. S. Ward} [Commun. Math. Phys. 128, No. 2, 319-332 (1990; Zbl 0707.32007)], the author applies Horrock's monad construction to the uniton bundles -- which were proven in [\textit{C. K. Anand}, Commun. Anal. Geom. 3, No. 3, 371-419 (1995; Zbl 0848.58013)] to be isomorphic to the based unitons, with the second Chern class corresponding to energy.
