Arctic convoys - - miscellany.
1. Those sailor in the water either their ship sunk awaiting rescue or already demised [floaters] subjected to attack by the Greenland shark? Normally a shark only living the deepest depths [600 meters or greater] but coming to the surface to scavenge and take advantage of a situation, a food source normally not obtainable. Greenland sharks known to attack warm blooded prey [seals most of the time, humans during the time of the convoys]. Those in the water at the risk drowning, freezing to death, OR BEING EATEN!
2. NAGS detachments [Naval Armed Guard Service] attached to American merchant marine vessels authorized if and when the necessity required, according to their own discretion, to break open a cargo and use what ever war munitions or armaments found to be present and suitable for defense.
3. Soviet light-bomber/heavy fighter Petlyakov Pe-3bis aircraft almost as an afterthought configured for the air defense mission, able to provide air cover for the convoys when in the vicinity and range of Soviet northern airfields and ports.
4. PQ is properly designated and notated as PQ. [Papa Quebec period]. PQ.13, PQ.17, etc. PQ outward bound, QP return.
5. From December 1942 until the end of the war the Arctic convoys referred to as JW [outward bound] and RA [return].
6. There is a certain appeal to naval warfare of the arctic convoy variety period? A clean fight, armed military men against other armed military men, civilians not in the line of fire or involved, damage to civilian property nil to negligible, etc. NO or minimal atrocity, NO shirking your duty, NO distinction between combatant soldier and rear-echelon support troops, etc. Duty of this sort regardless of hazard has a certain attraction for a great many?
