With the war on the Western Front stalemating, Paul von Hindenburg, Commander-in-Chief of the German armies in the East, and his Chief of Staff, Erich Ludendorff, came up with a plan. The idea was to decisively defeat the Russians in East Prussia, so that overwhelming power could then be transferred to the Western Front. The battle that ensued was called the Second / Winter Battle of the Masurian Lakes.

On 13 February 1862, Union commanding General U.S. Grant's positioning was complete and the time had come to attack Fort Donelson. The Union forces had spent the 12th of February closing in from Fort Henry and exchanging picket fire with the Confederates manning the earthen works of Fort Donelson. The gunboats had also spent the 12th testing the river batteries and found them tough, but assumed they could be taken as Fort Henry's had been.

By early 1864, Lincoln was despairing that he could find no General to prosecute the Union's war against the South in the eastern theatre. All of his leaders around the Potomac seemed to be frozen with indecision and a fear of failure. Much to his delight, a plan from a junior Cavalry General, H. Judson Kilpatrick, came into his view through Secretary of War Stanton. Kilpatrick knew that his immediate superiors would either poo-poo the idea or steal it as their own, so he approached Lincoln's adminstration directly through back channels. Kilpatrick was proposing a daring raid into the mouth of the lion to snatch Federal prisoners held in deplorable conditions in Confederate held Richmond. Kilpatrick's plan suggested more as well. Stanton and Lincoln were attracted by the idea that a raid into Richmond, apart from freeing prisoners, would also serve as a huge propaganda victory. Kilpatrick was summoned to Washington for a private meeting with Stanton and given the go ahead.

By early 1915, the lines in northern France had become static and the trench warfare that WWI is known for had commenced. Many soldiers and officers found themselves not only green, but found their senior leadership green in the tactics of the trench as well. New ideas had to be considered and new tactics developed to break the enemy lines for any offensive to succeed. The British First Army, under the command of the often maligned General Douglas Haig, was given the task of taking the immediate German positions, Neuve Chapelle and finally Aubers ridge. The First Army was made up of British, Canadians and Indians.

Although the battle is not often associated with the major battles of the First World War, it is highly significant in the analysis of the planning, technology and tactical advances of the time. The battle exhibited major breakthroughs in four key areas.

The early part of the American Revolutionary War was fought mostly in the North of the colonies, but after a series of defeats, the British decided to focus on the southern colonies in their persistant belief that Loyalist sympathies ran deeper there than the North. The British had built up a string of victories in the south by early 1781 by chasing down southern militias and defeating them one by one. General Washington sent one of his best Generals, Nathaniel Greene south to revive the Patriot effort. Greene had tried to separate his forces and hoped to catch the British off guard by making them attack him piecemeal. This had had some success, namely at Cowpens two months earlier, but it was getting harder and harder to avoid a major showdown with the British main force.

Before Gettysburg came the preparation of the route north.

Since its shameful fall in August 1812 with scarcely a shot fired in defense, the Americans wanted Detroit back. So embarrased by it, a winter campaign was conceived to win it back. William Henry Harrison, the hero of Tippacanoe, was selected to take back the area and further the American goals in the War of 1812. Harrison's second in command was General James Winchester. The two split their forces to move on Detroit.
