History of the 27th Infantry Division
The New York Division


Mobilization and Service in World War I

Called into federal service on July 15, 1917, the Twenty-Seventh Division hastily recruited to increase its numbers and late in August, was concentrated at Camp Wadsworth, near Spartanburg, SC, for intensive training. In the spring of 1918, the division began its movement toward embarkation camps. The division’s advance detachment left Hoboken on May 2 and arrived at Brest, France, May 10, 1918. Late in June the last units of the Twenty-Seventh Division had arrived safely overseas.

Until July 24 the division was in the final stages of training under British mentors, in Picardy and Flanders. On July 25th, the 27th Division less its artillery brigade and 102nd Ammunition Trains, occupied the Dickebusch Lake and Scherpenberg sectors in Flanders. In just over a month, this operation merged into the Ypres-Lys action, and then, from August 19 to September 3, the 27th was on its own.

The great Somme "push," lasting from September 24 to October 1, saw the 27th engaged in severe fighting along the Saint Quentin Canal Tunnel -- one of the out-lying strong points of the supposedly impregnable Hindenburg Line. Following heavy losses, the 27th was placed into reserve for rest and replacements at the conclusion of the first phase of the Somme Push. Six days later the Twenty-Seventh Division was back into action again, moving steadily toward Busigny on the heels of the retiring Germans.

The 27th Division had, in conjunction with British forces and the 30th Division, American Expeditionary Forces, had accomplished the supposedly impossible by cracking the vaunted Hindenburg line wide open.

The 52d Field Artillery Brigade and the 102nd Ammunition Train of the New York Division had not gone with the rest of the Twenty-seventh Division to the British front in Flanders. They had moved up on October 28, to support the Seventy-Ninth Division in the Argonne.

Meanwhile the Twenty-Seventh Division units which had seen heavy action in Flanders, had moved back to an area near the French seaport of Brest.

World War II Service

The 27th Infantry Division was federalized for service on October 15th, 1940 and initially commanded by Major General William Haskell. At this time it still retained its WWI organization of two brigades and four regiments. The 53rd Brigade consisted of the 105th and 106th Infantry regiments while the 54th Brigade contained the 108th and 165th Infantry regiments. Following a lengthy period of maneuvers and training, the 27th was ordered to California in December following the Japanese bombing of Pearl Harbor. While in California the 27th awaited orders to ship out and concentrated on bringing itself up to the authorized field strength of 1,012 officers and 21,314 enlisted men. The division’s strength had been reduced by discharges to around 14,000 men. The first elements of the division boarded ships bound for Hawaii on February 27th 1942, the first Infantry Division to leave the states following Pearl Harbor.

The division remained on Hawaii for a number of months, during which time it was triangularized, with the 108th Infantry regiment being reassigned to the 40th Division. A division that has been triangularized has been given three infantry regiments instead of the four of a square division. This final reorganization dismantled the brigade structure and again dropped the division’s strength to 14,000 men. Following the reorganization, the 27th Division was shifted to Oahu, where it would relieve the 25th Infantry Division, which was slated to join the U.S forces fighting in Guadalcanal. For most of its time in Hawaii, the 27th was under the command of Brigadier General Ralph Pennel.

On November 20th 1942, the 27th Infantry Division embarked on its first combat assignment, the capture of the coral atoll of Makin. The 27th also had a new division commander, Major General Ralph Smith. Units from the 27th Division also occupied the Majuro atoll on February 1st 1944 and successfully assaulted Eniwetok Island on February 19th of the same year. In June 1944, the division landed on Saipan, where its regiments fought together for the first time as a full division. Following Saipan the division was rested and reinforced at Espirto Santo for seven months before any further operations. During this time the 27th received its final division commander, Major General George Griner Jr. On April 12th, 1945 the division landed on Okinawa, where it would remain until September when it was sent to Japan briefly for garrison duty. The division was mustered out in late December of the same year. Since its arrival in the Pacific, the 27th Infantry Division had suffered 1,512 killed in action, 4,980 wounded in action and 332 who later succumbed to their wounds.

General Smith had been removed from command following a dispute with the aggressive and eccentric Marine commander, General Holland “Howling Mad” Smith who had been in overall command of the Saipan invasion. Holland Smith claimed that Ralph Smith had disregarded orders and mishandled the 27th Division, prompting the relief order. Later court of inquiry showed that the charges were for the most part unsubstantiated and General Ralph Smith was quickly given a new command.

The 27th returned to the states for deactivation in December 1945, the longest serving National Guard unit.

In late 1967 or early 1968, the 27th Armored Division was deactivated and reorganized as a Brigade of the 50th Armored Division. Prior to this time the Combat Commands had been replaced by Brigades in the Armored Divisions. Many units were deactivated, and others were re-assigned to the command of the 42nd Infantry Division, also assigned to the New York National Guard.

The 27th Brigade was reconstituted as a Separate Infantry Brigade (Light) in the 1980s and was originally established as a "round-out" Brigade to the Army’s 10th Mountain Division (Light Infantry) at Fort Drum.

In the 1990s, the Army National Guard nationwide was reorganized and the 27th was established as one of 15 separate “Enhanced” brigades, subject to priority call up in the event of a federal mobilization.

In 1998, the 27th Brigade was committed to disaster recovery operations in the New York’s North Country following a devastating ice storm which struck in January.  The 27th was called again for state emergency response in the wake of a destructive wind storm which struck Syracuse on Labor Day that year forcing an early close to the New York State Fair.

In the summer of 2001, the 27th Brigade deployed for an intense three-week training period at the U.S. Army’s Joint Readiness Training Center at Fort Polk, LA. Nearly 4,000 Soldier for the New York Army National Guard participated, making it the largest single exercise for the New York National Guard since World War II. The terrorist attacks of 9-11, 2001 struck within weeks of the units return home.

Following extensive state and federal active duty for Home Land Defense in response to the terrorist attacks of 9-11, 2001 subordinate units of the 27th underwent individual call ups for Operation Iraqi Freedom in 2003. In 2006, following the return of most New York National guard units from federal Active Duty in Iraq, the New York Army National Guard was “re-set” and the 27th was reorganized as an Infantry Brigade Combat Team.

History of the Orion
Shoulder Insignia

The three letters together form the monogram N .Y. D., standing of course for "New York Division."

Stars  Stars

These seven stars represent the brighter stars of the constellation Orion. They are included in the insignia as a compliment to Major-General O'Ryan, who has commanded the New York Division for seven years. When these units are all assembled as shown here, we have the complete insignia of the 27th division (now the 27th Brigade) -- probably the most unique insignia of any American Army Unit.

Astronomy Played a Part In Designing Insignia Of 27th

From an unsigned article in the National Tribune, Thursday, December 21, 1933

Astronomy furnished the inspiration for the distinctive shoulder patch insignia of the Twenty-seventh Division, American Expeditionary Forces, writes Herbert E. Smith in the Army Recruiting News. The division of New York National Guard men adopted Orion, the Seven Sisters of the Pletsdes--as a part of its finished design for a shoulder patch. The design was approved in 1918.

On a circled background of jet black appeared these seven stars in red, with the monogram NYD (New York Division) likewise in red. The colors, black and red, also have special significance. The black stands for iron and the red for the blood.


Another interesting coincidence lies in this design.  The Orion corresponds with the name O'Ryan, the 27th Division Commander Maj. Gen. John F. O'Ryan, the general who took the New Yorkers over to Europe during World War One and brought them back.
