At the Battle of Omdurman (2 September 1898), an army commanded by the British General Sir Herbert Kitchener defeated the army of Abdullah al-Taashi, the successor to the self-proclaimed Mahdi, Muhammad Ahmad. Kitchener was seeking revenge for the death of General Gordon in 1884.〔(【引用サイトリンク】title=This Sceptred Isle, Battle of Omdurman 1898, Episode 68 )〕 It was a demonstration of the superiority of a highly disciplined army equipped with modern rifles, machine guns and artillery over a vastly larger force armed with older weapons, and marked the success of British efforts to re-conquer the Sudan. However, it was not until the 1899 Battle of Umm Diwaykarat that the final Mahdist forces were defeated. Omdurman is today a suburb of Khartoum in central Sudan, with a population of some 1.5 million. The village of Omdurman was chosen in 1884 as the base of operations by the Mahdi, Muhammad Ahmad. After his death in 1885, following the successful siege of Khartoum, his successor (''Khalifa'') Abdullah retained it as his capital. ==Battle account== The battle took place at Kerreri, north of Omdurman. Kitchener commanded a force of 8,000 British regulars and a mixed force of 17,000 Sudanese and Egyptian troops. He arrayed his force in an arc around the village of Egeiga, close to the bank of the Nile, where a twelve gunboat flotilla waited in support,〔 facing a wide, flat plain with hills rising to the left and right. The British and Egyptian cavalry was placed on either flank. Abdullah's followers, known as ''Ansar'' and sometimes referred to as ''Dervishes'', numbered around 50,000,〔(【引用サイトリンク】title=Sudanese honour warriors who fell fighting British )〕 including some 3,000 cavalry. They were split into five groups—a force of 8,000 under Osman Azrak was arrayed directly opposite the British, in a shallow arc along a mile (1.6 km) of a low ridge leading onto the plain, and the other Mahdist forces were initially concealed from Kitchener's force. Abdullah al-Taashi〔 and 17,000 men were concealed behind the Surgham Hills to the west and rear of Osman Azrak's force, with 20,000 more positioned to the north-west, close to the front behind the Kerreri hills, commanded by Ali-Wad-Helu and Sheikh ed-Din. A final force of around 8,000 was gathered on the slope on the right flank of Azrak's force. The battle began in the early morning, at around 6:00 a.m. After the clashes of the previous day, the 8,000 men under Osman Azrak advanced straight at the waiting British, quickly followed by about 8,000 of those waiting to the northwest, a mixed force of rifle and spear-men. The 52 quick firing guns of the British artillery opened fire at around ,〔(【引用サイトリンク】title=Omdurman 1898 )〕 inflicting severe casualties on the Mahdist forces before they even came within range of the Maxim guns and volley fire. The frontal attack ended quickly, with around 4,000 Mahdist casualties; none of the attackers got closer than 50 m to the British trenches. A flanking move from the Ansar right was also checked, and there were bloody clashes on the opposite flank that scattered the Mahdist forces there. Kitchener was anxious to occupy Omdurman before the remaining Mahdist forces could withdraw there. He advanced his army on the city, arranging them in separate columns for the attack. The British light cavalry regiment, the 21st Lancers, was sent ahead to clear the plain to Omdurman. They had a tough time of it. The 400-strong regiment attacked what they thought were only a few hundred dervishes, but in fact there were 2,500 infantry hidden behind them in a depression. After a fierce clash, the Lancers drove them back (resulting in three Victoria Crosses being awarded to Lancers who helped rescue wounded comrades).〔(【引用サイトリンク】title=Charge of the 21st Lancers at Omdurman, 2 September 1898. )〕 One of the participants of this fight was Lieutenant Winston Churchill.〔 On a larger scale, the British advance allowed the Khalifa to re-organize his forces. He still had over 30,000 men in the field and directed his main reserve to attack from the west while ordering the forces to the northwest to attack simultaneously over the Kerreri Hills. Kitchener's force wheeled left in echelon to advance up Surgham ridge and then southwards. To protect the rear, a brigade of 3,000 mainly Sudanese, commanded by Hector MacDonald, was reinforced with Maxims and artillery and followed the main force at around . Curiously, the supplies and wounded around Egeiga were left almost unprotected. MacDonald was alerted to the presence of around 15,000 enemy troops moving towards him from the west, out from behind Surgham. He wheeled his force and lined them up to face the enemy charge. The Mahdist infantry attacked in two prongs, Lewis's Egyptian Brigade managed to hold its own〔 but MacDonald was forced to repeatedly re-order his battalions. The brigade maintained a punishing fire. Kitchener, now aware of the problem, "began to throw his brigades about as if they were companies".〔Winston S. Churchill (The Battle of Omdurman, 1898 )〕 MacDonald's brigade was soon reinforced with flank support and more Maxim guns and the Mahdist forces were forced back; they finally broke and fled or died where they stood. The Mahdist forces to the north had regrouped too late and entered the clash only after the force in the central valley had been routed. They pressed Macdonald's Sudanese brigades hard, but Wauchope's brigade with the Lincolnshire Regiment was quickly brought up and with sustained section volleys repulsed the advance. A final desperate cavalry charge of around 500 horsemen was utterly destroyed. The march on Omdurman was resumed at about 11:30. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Battle of Omdurman」の詳細全文を読む スポンサード リンク
