A vivid and unflattering description of Thomas Robertson is included in the journal of Ensign Abel Dottin William Best of the 80th regiment who was a member of the Guard on the James Pattison in 1837 and met the surgeon when he first came on board at Deptford.....'The Surgeon' A raw boned sandy hair'd Sawney his appearance not by any means prepossessing; a kind of careworn countenance embellished with a small pair of grey eyes and a huge nose which I suppose nature intended for a Roman but the delicacy of its shape having been destroyed and its having a considerable inclination towards the left ear its effect is not good and it has the appearance of a handle to his whole person I strongly suspect that it has on some occasion been smashed, his disposition I should pronounce on so short an acquaintance to be a singular compound of easiness, obstinacy and peevishness, he has a wife at present on board and is anxious to arrive at Sheerness (I don't mean to insinuate) The name this animal
rejoices in is Robertson. He is commanding officer. I will now introduce you to (in truth) his better half, one of the coarsest Irish women I ever met with, she is what a certain friend of ours would call a 'horid great hog' of a woman she weighs I suppose 14 stone and has evidently a temper. I find some amusement in teasing her as she flares up like a flambeau. The subject is disagreable & I shall dismiss it as I hope to dismiss her, shortly. She goes at Sheerness
