Military law allowed swift prison sentences to be passed. Thousands of Arabs were held in administrative detention, without trial, and without proper sanitation, in overcrowded prison camps.The British had already formalised the principle of collective punishment in Palestine in the 1924–1925 Collective Responsibility and Punishment Ordinances and updated these ordinances in 1936 with the Collective Fines Ordinance. These collective fines (amounting to £1,000,000 over the revolt) eventually became a heavy burden for poor Palestinian villagers, especially when the army also confiscated livestock, destroyed properties, imposed long curfews and established police posts, demolished houses and detained some or all of the Arab men in distant detention camps.Full martial law was not introduced but in a series of Orders in Council and Emergency Regulations, 1936–37 'statutory' martial law, a stage between semi-military rule under civil powers and full martial law under military powers, and one in which the army and not the civil High Commissioner was pre-eminent was put in place. Following the Arab capture of the Old City of Jerusalem in October 1938, the army effectively took over Jerusalem and then all of Palestine.The main form of collective punishment employed by the British forces was destruction of property. Sometimes entire villages were reduced to rubble, as happened to Mi'ar in October 1938; more often several prominent houses were blown up and others were trashed inside. The biggest single act of destruction occurred in Jaffa on 16 June 1936, when large gelignite charges were used to cut long pathways through the old city, destroying 220–240 buildings and rendering up to 6,000 Arabs homeless. Scathing criticism for this action from Palestine Chief Justice Sir Michael McDonnell was not well received by the administration and the judge was soon removed from the country. Villages were also frequently punished by fines and confiscation of livestock. The British even used sea mines from the battleship HMS Malaya to destroy houses.In addition to actions against property, a large amount of brutality by the British forces occurred, including beatings, torture and extrajudicial killings. A surprisingly large number of prisoners were "shot while trying to escape". Several incidents involved serious atrocities, such as massacres at al-Bassa and Halhul. Desmond Woods, an officer of the Royal Ulster Rifles, described the massacre at al-Bassa:Now I will never forget this incident ... We were at al-Malikiyya, the other frontier base and word came through about 6 o'clock in the morning that one of our patrols had been blown up and Millie Law [the dead officer] had been killed. Now Gerald Whitfeld [Lieutenant-Colonel G.H.P. Whitfeld, the battalion commander] had told these mukhtars that if any of this sort of thing happened he would take punitive measures against the nearest village to the scene of the mine. Well the nearest village to the scene of the mine was a place called al-Bassa and our Company C were ordered to take part in punitive measures. And I will never forget arriving at al-Bassa and seeing the Rolls Royce armoured cars of the 11th Hussars peppering Bassa with machine gun fire and this went on for about 20 minutes and then we went in and I remembered we had lighted braziers and we set the houses on fire and we burnt the village to the ground ... Monty had him [the battalion commander] up and he asked him all about it and Gerald Whitfeld explained to him. He said "Sir, I have warned the mukhtars in these villages that if this happened to any of my officers or men, I would take punitive measures against them and I did this and I would've lost control of the frontier if I hadn't." Monty said "All right but just go a wee bit easier in the future."As well as destroying the village the RUR and men from the Royal Engineers collected around fifty men from al-Bassa and blew some of them up with explosion under a bus. Harry Arrigonie, a policeman who was present said that about twenty men were put onto a bus; those who tried to escape were shot and then the driver of the bus was forced to drive over a powerful land mine buried by the soldiers which completely destroyed the bus, scattering the mutilated bodies of the prisoners everywhere. The other villagers were then forced to bury the bodies in a pit.Despite these measures Lieutenant-General Haining, the General Officer Commanding, reported secretly to the Cabinet on 1 December 1938 that "practically every village in the country harbours and supports the rebels and will assist in concealing their identity from the Government Forces." Haining reported the method for searching villages:A cordon round the area to be searched is first established either by troops or aircraft and the inhabitants are warned that anybody trying to break through the cordon is likely to be shot. As literally hundreds of villages have been searched, in some cases more than once, during the past six months this procedure is well-known and it can be safely assumed that cordon-breakers have good reasons for wishing to avoid the troops. A number of such cordon-breakers have been shot during searches and it is probable that such cases form the basis of the propaganda that Arab prisoners are shot in cold blood and reported as "killed while trying to escape". After the cordon is established the troops enter the village and all male inhabitants are collected for identification and interrogation.The report was issued in response to growing concern at the severity of the military measures amongst the general public in Great Britain, among members of the British Government, and among governments in countries neighbouring Palestine.In addition to actions against villages the British Army also conducted punitive actions in the cities. In Nablus in August 1938 almost 5,000 men were held in a cage for two days and interrogated one after another. During their detention the city was searched and then each of the detainees was marked with a rubber stamp on his release. At one point a night curfew was imposed on most of the cities.It was common British army practice to make local Arabs ride with military convoys to prevent mine attacks and sniping incidents: soldiers would tie the hostages to the bonnets of lorries, or put them on small flatbeds on the front of trains. The army told the hostages that any of them who tried to run away would be shot. On the lorries, some soldiers would brake hard at the end of a journey and then casually drive over the hostage, killing or maiming him, as Arthur Lane, a Manchester Regiment private recalled: ... when you'd finished your duty you would come away nothing had happened no bombs or anything and the driver would switch his wheel back and to make the truck waver and the poor wog on the front would roll off into the deck. Well if he was lucky he'd get away with a broken leg but if he was unlucky the truck behind coming up behind would hit him. But nobody bothered to pick up the bits they were left. You know we were there we were the masters we were the bosses and whatever we did was right ... Well you know you don't want him any more. He's fulfilled his job. And that's when Bill Usher [the commanding officer] said that it had to stop because before long they'd be running out of bloody rebels to sit on the bonnet.British troops also left Arab wounded on the battlefield to die and maltreated Arab fighters taken in battle, so much so that the rebels tried to remove their wounded or dead from the field of battle. Sometimes, soldiers would occupy villages, expel all of the inhabitants and remain for months. The Army even burned the bodies of "terrorists" to prevent their funerals becoming the focus of protests.Nevertheless, it has been argued that British behaviour overall was good compared to most other examples where a foreign army suppressed a popular insurgency.
