What weapons did Altmark's boarding parties carry?

Did the boarding crew at the Altmark incident carry cutlasses?

Some cruiser personnel may have carried swords, but destroyer parties more often relied on firearms, knives, and improvised close-combat weapons.

Cruiser personnel were more likely to carry swords, while destroyer sailors favored pistols and rifles. Later discussion adds sabres, blackjacks or brass knuckles, long knives, and improvised engineering tools to the likely mix. The evidence does not support a single uniform loadout for every boarding party. Differences in tradition and training mattered, as did the broad technical duties expected from a destroyer's smaller officer complement.
