All that is known about Tambornini is that which he states himself, which is that at the time of publication he was a retired lieutenant of the Royal Navy and fencing master at the Royal Naval College in Genoa.
The only notable mention of Tambornini's treatise outside of bibliographic summaries comes from Alberto Marchionni, in an addendum to his 1847 treatise Trattato di Scherma, republished some time in the mid-to-late 1860s. Marchionni is full of praise for the treatise, calling it one of the best works on sabre published to date:
Various Fencing Treatises, both for sword and sabre, have been published in recent times, and among these I have been able to acquire that of Mr. Carlo Tambornini, retired Lieutenant and professor of Fencing at the Royal Naval College in Genoa, published in said City by Tipografia Ponthonier e Compagni in 1862. Having read on page two his desire to hear the judgement of his Colleagues, I speak for myself impartially in saying that it seems to me one of the best Sabre Treatises to be published, and it can truly be said to be elementary where its very correct precepts are indicated, both in offensive and defensive actions, on attacking in the tempo of the Opponent's feints and blows, and on the appuntate and remises with the hand. Attentively studying this treatise can be very useful for those who dedicate themselves to this type of fencing.
In addition to the appreciable amount of tactical advice he gives for sabre fencing, Tambornini also gives some advice on sabre vs. sword and sabre vs. bayonet.
