It appears that while Everest and Waugh both extolled him for his exceptional mathematical abilities, his relations with the colonial administration were far from cordial. Two specific instances are on record.
In 1851 a voluminous Survey Manual (Eds. Capt. H. L. Thullier and Capt. F. Smyth) was published by the Survey Department. The preface to the Manual clearly and specifically mentioned that the more technical and mathematical chapters of the Manual were written by Babu Radhanath Sikdar. The Manual proved to be immensely useful to surveyors. However, the third edition, published in 1875 (i.e., after Sikdar's death) did not contain that preface, so that Sikdar's memorable contribution was de-recognized. The incident was condemned by a section of British surveyors. The paper Friend of India in 1876 called it 'robbery of the dead'.
It is also on record that Sikdar was fined a sum of 200 rupees by the British court in 1843 for having vehemently protested against the unlawful exploitation of survey department workers by the Magistrate Vansittart. The incident was reported in detail in The Bengal Spectator edited by another great Derozian Ramgopal Ghosh.
In 1854, he along with his Derozian friend Peary Chand Mitra started the Bengali journal Masik Patrika, for the education and empowerment of women. He used to write in a simple and uncluttered style that was rather atypical for the age.
Sikdar had retired from service in 1862.
He died on 17 May 1870 at Gondalpara, Chandannagar in his villa by the side of the Ganga.
