Altmark receives more prisoners from Graf Spee, including captured merchant seamen and some officers. The supply ship already has a couple of machine guns from the raider, and further weapons may have followed at this meeting. The date of that additional transfer is uncertain: some chronologies place it earlier or later than 24 November. This rendezvous seems the likeliest opportunity because the ships faced less immediate pressure and were receiving substantial replenishments, so the prisoner movement is more securely dated than the possible weapons transfer.

Altmark takes prisoners and perhaps more weapons
Graf Spee transfers more captured merchant seamen and officers to Altmark, which already carries machine guns supplied by the raider. Further guns may have passed between the ships during the same quiet rendezvous, but their timing is uncertain.
