After gaining the required letter of recommendation, due to his ability to speak German, French, Arabic and English, Symes was commissioned as a Lieutenant into the Royal Navy, operating Motor Torpedo Boats (MTBs) in the Mediterranean while based in Alexandria.[2][3] Quickly rising to command his own boat, he broke anti-torpedo measures in a raid on Tripoli.[2][3] After rising to the rank of Lieutenant Commander, he took part in protecting the landings that led to the liberation of Crete.[2][3]
