Camp near White Oak Church. Va. 77 th Regt. N.Y.S.V. May 16th 1863 Dear Sir According to your request I improve the present opportunity to in- form you of our late moves as I thought it might interest you. April the 28th orders came to march & in a drench- ing rain we struck tents & started once more for the Rappahannack. We bivowaced for the night on the bank of the river two miles below Fredricks- burg & next morning the 1st division of our troops crossed with but little opposition. The first Army Corps crossed one mile further down & thus we remained until Saturday night when the remaining two divisions of our corps crossed also. Friday, the day before this however the 1st Army corps were recalled from across the river & sent to join Hook- er thus leaving the 6th corps all alone. Sunday morn- ing we were drawn up in lines of battle with our right between the city of Fred- ricksburg & the heights. Daylight revealed us to the enemy upon our right advancing we were opened upon with musket- ing from the enemy under cover of their rifle pits & their artillery from the heights. Our right not being able to drive them from their works, fell back a short distance & nothing further occured un- til noon but a little ar- tillery firing. At noon our right again advanced & stormed the heights in their front capturing their guns & taking many pris- oners. The 77th which was to the left & deploy- ed as skirmishers were now ordered to advance from the rifle pits from which they had driven the enemy about an hour be fore & storm the heights in our front also. The plain at this place was 1½ mile wide & about one mile from the rifle pit in which we lay to the heights. As we advanced they shelled us most terrificly & as we neared the heights they used grape & can- ister which fell around us like hail. We had reach- ed a point to within 100 rods of the heights when their fire was so heavy that we could endure it no longer. Just to our front was a deep ditch filled with water & into this we plunged glad to escape for a moment their murderous fire. We lay here for about ten minutes when we again advanced & stormed the heights capturing four brass 12 pounders & many prisoners. We could proceed no further for we had lost heavily & were completely exhausted. Up to this time we had been un- supported but reinforce- ments now coming up with artillery they persued the enemy for more than a mile when they again made a stand & repulsed our forces with heavy loss. Darkness now coming on the bloody scene closed for the day. Next morning the booming of cannon to our rear & the bursting of shells over our heads announced to us that the enemy had regained pos- session of the heights & were between us & the river. We immediately formed a new line with both flanks resting on the river the 77th being on the left. All was comparatively quiet during the day until near night when the enemy being heav- ily re-enforced so as to out number one to five & against this overwhelming force we could not long stand. They drove us for more than a mile through woods thick with under- brush & filled with deep revines, The 77th being in the front when attack- ed now brought us to the rear & exposed to the fire of the enemy who persued us closely. It was now after dark but still firing was keep us more or less until we were all across the river which was about two oclock in the morning. We were once more on our own ground. The fight had been a hard one & we had lost heavily espec- ialy in prisoners during the second days fight. The loss of our regiment was 119 in killed, wounded & pris- oners which was remark- ably small considering what we had been through for we had been to the front during most of the time. We lay at Bank's ford where we had recrossed the river for three days when we again returned to White Oak Church & within one mile of our old encamp- ment where we are now comfortable situated. Al- though we have been oblig- ed to fall back again this side of the river we feel con- fident that we have dealt the enemy a severe blow. The army have full confi- dence in Gen. Hooker & will be as willing to cross when he may again order as ever they were. We think that this can- not last much longer & for my part I care not how soon it can be brought to an honorable close. Some- thing must & shall be done this summer & may another winter behold us all with loved ones at home. Please write when you have the opportune- ity & inform me how the suit is progressing. I re- main your obediant ser- vant. Lyman Vandenburgh Sergeant Co, G 77th Regt.N.Y.S.V. Washington D.C.
