Kotra (ed - the village, not the tehsil) is a cantonment in the south-west of the State of Udaipur, Rajputana, situated in 24 deg 22 min N and 73 deg 11 min E., about 38 miles south-west of Udaipur city, and 34 miles south-east of the Rohera station on the Rajputana-Malwa Railway. A detachment (two companies) of the Mewar Bhil Corps is quartered here, and the officer commanding these is Assistant to the Political Suprintendent of the Hilly Tracts. The Kotra district or bhumat consists of 242 villages, with 16,738 inhabitants, more than two-thirds of whom are Bhils. These villages are owned by the three Girasia chiefs of Jura, Oghna, and Panarwa, who pay a small tribute or quit-rent to the Mewar Durbar.

2. Missionary work in Kotra

There is a good sized section on missionary efforts in Kotra in the late 1800 and early 1900 in a book Battling And Building Among the Bhils preserved in electronic format by the University of Toronto library(link).

In 1891 Mr. Thompson, after several previous visits, opened work at a village called Kotra, situated about fifty miles from Kherwara, which offered many facilities for reaching a large tract of hitherto unevangelized country. Kotra comprises two independent villages, one a small cantonment of the Mewar Bhil Corps, which lies on the right bank of the Pamri in Rajputana, and the other a simple Bhil village in Gujarat on the east of the river. It was in the latter that Mr, Thompson erected a rest house and a school, and the Gospel message was proclaimed there until 1900.

The hill districts of Oudeypore (ed - Udaipur) to the south and south-west (ed - i.e., Kherwara and Kotra) are inhabited by the wild and turbulent tribes of the Bheel and Grassia (ed - Garasia) under Rajpoot chiefs owing a nominal allegiance to Oudeypore, holding the right of property in the land over which the maharanas have no power, and levying black mail on neighboring villages and a tax on the passage of goods and travellers....accordingly it was proposed in 1838 to raise a Bheel corps to be stationed in these districts.
