In his letter of introduction to Brigadier General Jacob Lauman, his qualifications were described as having served "in the artillery abroad."
His mother, Johann Philipine Dorothea, later immigrated to the United States in 1848, but as the wife of a British merchant, John Heanes.
Julius married Sophia Rosa Lueber on November 25, 1858, at Holy Trinity Church of Georgetown in Washington, DC.
Her father, Francis Lueber (1791–1852), emigrated from Austria, and was a well-to-do merchant; her mother, Hellen Maria Simpson (1809–1890) came from the District of Columbia and was descended from the original English settlers in Maryland.
After Julius' death, his widow did not remarry, but continued to live in Georgetown with her widowed mother, sisters, and brother until her death on September 29, 1916, and is buried in Holy Rood Cemetery in Washington, D.C.. Sophia was the niece of the American portrait artist, James Alexander Simpson, and first cousin to another portrait artist, Charles S. Hein, and his brother, Lt. Col. Otto L. Hein.
In late 1853, the Koszta Affair had militated many Americans to form societies supporting the U.S. government's interest against the claims of the Austrian Empire.
One of the aims of the society was to monitor political situations around Europe through committees of correspondence, and note any violation of the rights of naturalized American citizens.
Kroehl brought to the attention of the society that one Henry von Rensche was arrested by Prussian authorities for crimes against the Crown despite being a naturalized citizen.
The Society of Universal Democratic Republicanism included Charles F. Henningsen, Hugh Forbes and Henry H. Morange as members.
However, when Kroehl was ordered to support Union forces during the Vicksburg Campaign of 1863, he was directed to bring with him photographic equipment after spending one month being trained on their use by members of the U.S. Coast Survey in Washington, DC.
The City of New York, in order to improve safety during its growth, laid out a series of fire watch towers.
[3] Comparing the structure and techniques of this tower with those designed and constructed by Bogardus show many similarities, especially in the method of bolting joints together.
On 21 May 1853, Cornelius Vanderbilt's yacht, the North Star, ran aground on Corlear's Hook and had to go back to dry dock for repairs, though no material damage was sustained.
The area was then called "Vanderbilt Rock" with the expectation that City and State officials would arrange its removal as a hazard to navigation.
The maritime hazard of Diamond Reef lies at the entrance to the East River between Governor's Island and Lower Manhattan.
This effort was accomplished by lowering a canister of powder onto the rock at flood tide, then backing away a safe distance, detonating it with a galvanic battery.
Peter Cooper, as president of the New York and Newfoundland Telegraph Company, hired H&K to blast Merlin Rock, which lies at the western end of the narrows in St. John's Harbor, in June 1855.
During the demolition of Diamond Reef, H&K provided underwater explosives to the U.S. Navy for clearing obstructions in the Platte, Parana and Paraguay Rivers, should the ships encounter any.
Parmenter, a machinist from Troy, New York, contracted with the Navy Department to construct, erect and complete an iron roof for the victualling house at Norfolk Naval Shipyard in the amount of $18,000.
But the seizure of Norfolk by Confederate forces in April 1861 forestalled final completion of the project, with an amount owed to Parmenter.
In May 1861, Alexander Asboth proposed to the War Department for the formation of an all-arms brigade consisting of infantry, cavalry, artillery, engineers and pontoniers.
160 and its tender fell into the Potomac River near Alexandria in 40 feet of water when a sudden squall caused the barge to shift its cargo.

Kroehl served as a member of Admiral Porter's personal staff aboard the USS Black Hawk.
His duties appear to be varied, responding to Porter's needs at the time: First, working with the U.S. Coast Survey in developing navigation charts of the Mississippi to support naval operations.
During the Steele's Bayou Expedition he sank a coal barge on his own initiative which allowed the Union ships to retreat from a tenuous position.
During this time, he contracted malaria, and was honorably discharged on August 8, 1863, after being sent back to New York City by way of Cairo, Illinois.
[9] His widow, Sophia, argued that his death was from service-related malaria, citing witnesses who knew him during the Vicksburg campaign as well as medical statements.
As a Civil War veteran, his remains are expected to be re-interred in the Corozal American Cemetery, near the Panama Canal.
On top of that, she even had Archbishop John Ireland of the Roman Catholic Archdiocese of St. Paul, Minnesota, to lobby personally with the bureau.
