When you hold the line, you make sure you maintain an existing opinion, position, or status regardless of what outside or opposing forces may try to do. Even the military has a mission referred to as a Hold The Line mission.
The Pittsburg Post-Gazette reported on what was going on in Murrysville in their November 20, 2013 edition. It was all about mills and taxes: mills for the general tax rate, mills for capital improvements, mills for municipal debt repayment, mills for road improvements. It seemed that if there was a mill, there was a discussion. The opening paragraph read as follows:
Murrysville council members reviewed recommendations from the administration to hold the line on taxes for the coming year, giving unanimous approval Wednesday night to advertise an ordinance setting the tax rate at 12.15 mills for 2014.
Back on December 1, 1971 the Spokesman-Review reported on President Richard Nixon’s announced intention to veto his own tax cut bill. It seems that what had happened to the President’s bill was that the Senate attached additional provisions to the bill that, if the bill went through, would result in another $11 billion dollars added to the deficit. The story was entitled, “Hold The Line.”
During World War II, what was happening on the front was vigorously reported in the newspapers regardless of what country was reporting on the war. The Calgary Herald edition of October 27, 1941 carried international news that was cabled from the Calgary Herald‘s London bureau courtesy of the London Times. As the Russian campaign continued, battles raged near Rostov-on-Don anda round Kharkov. The Germans hoped to reach Roslov to cut the main railway line from the Caucasus to Moscow. The report included this news byte:
When the Red armies failed to hold the line of the lower Dnieper, German forces, with the aid of Hungarians, Rumanians and Italians were able to undertake a determined eastward drive and Marshal Budenny had no adequate line of defence available until he reached the River Don.
When the New York Times ran an article entitled, “Boxers Engaged In Big Battle” on June 8, 1900 many were alarmed at the events unfolding in China. The article claimed that the Daily Express had sent the following dispatch from Shanghai on June 7 with regards to the results of the Dowager Princess’s orders to General Neih-Si-Chong to take 3,000 men and protest the railroad at Peking. British was unable to send more than 900 troops as they were involved with the situation in South Africa, and the United States was urged to act. The article included this information:
Attempts to repair the damage to the railway between Tien-Twin and Peking have been frustrated by the Boxers who, thousands strong, hold the line against the engineers, gangs attacking the trains arriving.
Another show of force was reported in the American and Commercial Advertiser of August 23, 1864 — thanks to the New York Tribune newspaper — this time with regards to the skirmishes of the Fifth Corps against Rebel forces at Weldon Railroad just below Petersburg. The focus of this mission was to destroy the road completely this time. It was seen as a successful mission no three counts: It resulted in greater losses being inflicted than suffered; it prevented the Rebel forces from sending more troops into the Valley; and Fifth Corps achieved its main objective. The newspaper story reported the following in part:
Exactly one half of all the Rebel forces in Virginia are in the Shenandoah Valley awaiting Heridan. The other half hold the line from Richmond to Petersburg. From Gen. Birney’s Headquarters, the right of the line of operations, to Gen. Warren’s, the extreme left, is a distance of over twenty-five miles by the shortest roads. The whole distance is entrenched and two large rivers straddled. Grant having much the larger army, can afford to stretch the line of operations and thus attenuate Lee’s forces.
Jumping back to 1805, the idiom was used in “The Vindication of Mr. Maurice’s Modern India” also known as “A Vindication of the Modern History of Hindostan From The Gross Misrepresentations, And Illiberal Strictures of the Edinburgh Reviewers” by schoolmaster and former chaplain to the 87th regiment, Thomas Maurice. In his book, he wrote:
It seems however, by the Edinburgh standard of criticism, at least, that an author can no longer be permitted to mark out for himself the outline of any work which he may meditate, or of the limits by which his prudence may lead him to bound, or his temerity to extend his excursion in the wide field of literary research. The Reviewer must hold the line of demarcation, and let the author transgress it at his peril. The direst anathemas of critical vengeance, infallibly attend the slightest deviation.
The word hold is from the Old English word geheald which means keeping, custody, or guard and dates back to 1200, and the word line (as in demarcation) dates back to the middle of the 15th century. That being said, it doesn’t seem that the words met up and became an idiom until later. Although the idiom was used easily in Thomas Maurice’s book, and research hints at the idiom being used in the early 1700s, Idiomation was unable to find an earlier published version than the one in 1805. Taking into account that those who read Thomas Maurice’s book would have understood what he mean when he used the expression hold the line, it is most likely that the idiom hit its stride two generations prior to the publication date, putting it somewhere in the 1750s.
