During World War II, Operation Basalt was a small raid on the German occupied British Channel Island of Sark, on the night of 3/4 October, 1942.

It was conducted by ten men of the SOE's Small Scale Raiding Force, and No.12 Commando with the object of an offensive reconnaissance and capturing prisoners.

Nine of the raiders broke into the house of a local while the tenth went to a covert rendezvous with an SOE agent. The occupant of the house, Frances Pittard, proved very informative and advised there were about 20 Germans in the nearby Dixcart Hotel. She also declined an offer to take her back to England.

In front of the hotel was a long hut type building, apparently unguarded. This annex comprised a corridor and five rooms wherein were five sleeping Germans, none found to be officers. The men were roused and taken outside whereafter the Commandos decided to go on to the hotel and capture more of the enemy. To minimise the guard left with the captives, the Commandos tied the prisoners hands with the toggle ropes each carried a six foot length of, and required them to hold up their trousers. The practise of removing belts and/or braces and tearing open the fly was quite a common technique the Commandos used to make it as difficult as possible for captives to run away.

While this was being undertaken, one prisoner started shouting to alert those in the hotel and was instantly shot dead with a .38 revolver. The enemy now alerted, incoming fire from the hotel became considerable and the raiders elected to return to the beach with the remaining four prisoners. En route to the beach, three prisoners made a break. Whether or not some had freed their hands during the firefight is not established nor if all three broke at the same time. Two were believed shot and one stabbed. The fourth was conveyed safely back to England and proved a mine of information. The raiders also evacuated a SOE agent who had been posing as a Polish labourer among forced labour on the island.

A few days later the Germans issued a propaganda communiqué implying at least one prisoner had escaped and two were shot while resisting having their hands tied.

It is believed this instance of tying prisoner's hands contributed to Hitler's decision to issue his Commando Order instructing all captured Commandos or Commando type personnel be executed as a matter of procedure.
