Shortly afterwards, war broke out with the Ameers of Scinde, a large province occupying the basin of the lower Indus. The British commander, Sir Charles Napier, speedily proved to the enemy that the spirit of the British army had not failed since the days of Plassey. With a force of only 3000 men, he attacked and completely defeated two armies much superior in numbers (1843). The result of these two victories—Meanee and Dubba—was the annexation of Scinde to the British dominions.

The main stream of the Indus is formed by the junction of five smaller branches. The large and fertile tract of country watered by these tributary streams is named the Punjab, or the land of the 'five waters.' It was inhabited by a people called the Sikhs, who, at first a religious sect, have gradually become the bravest and fiercest warriors in India. They had a numerous army, which was rendered more formidable by a large train of artillery and numerous squadrons of daring cavalry.

After being long friendly to us, disturbances had arisen among them; the army became mutinous and demanded to be led against the British. Much severe fighting took place; at length, after a series of victories, gained mainly by the use of the bayonet, the British army pushed on to Lahore, the capital, and the Sikhs surrendered (1846).

Three years later they again rose; but after some further engagements, their main army was routed with great slaughter by Lord Gough, in the battle of Gujerat. The territory of the Punjab was thereupon added to our Indian empire.

The terrible famine which was passing over Ireland (1846-47), owing to the failure of the potato crop, had to be dealt with by the ministry. The sufferings of the Irish peasantry during this trying time were most fearful; and sympathy was keenly aroused in this country. Parliament voted large sums of money to relieve the distress as much as possible, the government started public works to find employment for the poor, and their efforts were nobly seconded by the generosity of private individuals. But so great had been the suffering that the population of Ireland was reduced from eight to six millions during this period.

The measure for which Peel's ministry will always be famous was the Repeal of the Corn-laws. The population of the country was rapidly increasing; and as there were now more mouths to fill, it became more than ever necessary to provide a cheap and plentiful supply of bread to fill them. For several years the nation had been divided into two parties on this question. Those who were in favour of protection for the British wheat-grower were called Protectionists, while those who wished to abolish the corn-duties styled themselves Free-traders.

In the year 1839 an Anti-Corn-law League had been formed for the purpose of spreading free-trade doctrines among the people. It had its headquarters at Manchester, and hence the statesmen who took the leading part in it were frequently called the 'Manchester Party.' There being no building at that time large enough to hold the meetings in, a temporary wooden structure was erected, the site of which is marked by the present Free-trade Hall. The guiding spirit of the league was Richard Cobden, a cotton manufacturer, who threw himself heart and soul into the cause. He was assisted by many other able men, the chief of whom was the great orator, John Bright. Branches of the league were soon established in all the towns of the kingdom, and a paid body of lecturers was employed to carry on the agitation and draw recruits into its ranks.

At the beginning of the year 1845, owing to the success of Peel's financial measures, the nation was in a state of great prosperity and contentment; and there seemed little hope that the repealers would be able to carry their scheme for some time to come. Before the year was out, however, the aspect of affairs was completely changed. As John Bright said years afterwards, 'Famine itself, against which we had warred, joined us.' There was a failure in the harvest, both the corn and potato crops being blighted. Things in this country were bad enough; but they were far worse in Ireland, where famine and starvation stared the people in the face. Under these circumstances the demand for free-trade grew stronger and stronger; and the league had the satisfaction of gaining over to its ranks no less a person than Sir Robert Peel himself.

When Peel announced his change of opinion in the House of Commons, the anger of the Protectionists, who were chiefly Conservatives, knew no bounds. They considered they had been betrayed by the leader whom they had trusted and supported. Mr Disraeli, in a speech of great bitterness, taunted the prime-minister with his change of views. His speech was cheered to the echo by the angry Protectionists; and from this moment Disraeli became the spokesman and leader of that section of the Conservative party which was opposed to repeal.

The next year a measure for the repeal of the corn-laws was introduced into parliament by the prime-minister. In spite of the fierce opposition of Mr Disraeli and his friends, it passed both Houses by large majorities. At the close of the debates, Peel frankly acknowledged that the honour of passing this great measure was due, not to himself, but to Richard Cobden. On the very day on which the Corn Bill passed the Lords, the Peel ministry was defeated in the Commons on a question of Irish coercion, and had to resign.
